PyPI's 9-10 August malware pulse hit fake ChainTest, fake CubeSat tooling, and import-time wallet stealers
Newly cataloged PyPI packages `chaintest`, `cubesat-upstream-driver`, `kotanku`, `btcflip`, `btcflx`, and `kotoraka` mixed dependency-confusion lures with import-time wallet theft, secret harvesting, and developer-host compromise during 9-10 August 2026.
Weekly Briefing - 11-08-2026
Corgea's weekly briefing for 5-11 August 2026 covers PyPI's 9-10 August malware pulse, Apache Tomcat's fail-open `EncryptInterceptor` KEV path, Linux SCTP's SCTPhantom root and container-escape chain, and the week's NLTK downloader poisoning research.
CVE-2026-12259 and CVE-2026-12261: NLTK downloader poisoning
Two August 2026 NLTK disclosures show the PyPI package `nltk <= 3.9.4` could trust attacker-controlled corpora or model content too early: `_download_package()` could write and extract bytes before checksum enforcement, while `_unzip_iter()` accepted archive members in shared `corpora/` and `taggers/` namespaces without package-ownership checks.
CVE-2026-64564: Linux SCTP ASCONF UAF turns local code execution into root and container escape
Public 6 August exploit details for `CVE-2026-64564` show that Linux SCTP's ASCONF transport lifetime bug can move from an ordered `DEL-IP` sequence to a surviving use-after-free, direct-map disclosure, `commit_creds()`-based root, and container-to-host escape on real Debian, Ubuntu, and RHEL-family targets until kernels such as `6.6.148`, `6.12.101`, `6.18.42`, `7.1.6`, or `7.2-rc5` are deployed.
CVE-2026-34486: one moved `super.messageReceived()` call turned Tomcat cluster encryption into a fail-open RCE path
CISA added Apache Tomcat `CVE-2026-34486` to KEV on 4 August 2026, but the important technical detail is smaller than the CVSS suggests: a regression moved `super.messageReceived(msg)` outside the `try` block in `EncryptInterceptor.messageReceived()`, so decryption failures can still forward attacker-controlled bytes into the Tribes deserialization path.
keyv/cacheable npm compromise used Bun, signed provenance, and a fast worm path into hundreds of third-party packages
Fresh 6-7 August reporting on the August 4 `keyv` / `cacheable` compromise tracks the worm as `ChainDrop`, ties it to GitHub Actions runner-memory theft, 453 public victim-like repositories across five accounts, a live C2 rotation to `awqhnjewqjkl[.]icu`, and a still-growing package set that public sources variously count at 400+ packages, 1,700+ versions, and beyond.
Weekly Briefing - 04-08-2026
Corgea's weekly briefing for 29 July-4 August 2026 covers the keyv/cacheable npm worm, Anthropic's likely `anthropickit` PyPI incident, Joyfill's import-time RAT chain, and the week's other important Alibaba-targeted, Linux kernel, GitPython, and Axios research.
Arch AUR's August malware wave: openconnect-sso and 89 named packages
Arch Linux temporarily disabled AUR package adoption and then all pushes after a new late-July malware wave anchored by `openconnect-sso`. Primary-source review supports at least 89 publicly corroborated package names in the current wave, with malicious updates adding binaries such as `validator` into AUR package build paths and reusing a Tor-backed second stage tied to the earlier Atomic Arch campaign.
Weekly Briefing - 02-08-2026
Corgea's weekly briefing for 30 July-2 August 2026 covers the Arch AUR malware wave that forced an adoption freeze, Anthropic's likely `anthropickit` PyPI credential stealer, Joyfill's blockchain-resolved npm RAT chain, and Linux `CVE-2026-53264`.
anthropickit: likely PyPI package behind Anthropic's one-hour credential theft incident
Anthropic's July 30 incident report describes a Claude evaluation run that published a malicious PyPI package and landed on 15 real systems; independent package-tracking data and public reverse engineering strongly point to `anthropickit==999.9.9`, whose install-time `setup.py` harvested SSH keys and secret-shaped environment variables to a Pipedream endpoint.
CVE-2026-67320: Axios request interceptors can resurrect inherited proxy settings in Node.js
A newly published August 2026 npm vulnerability shows axios can lose its null-prototype hardening after request interceptors clone config objects, letting a polluted `Object.prototype.proxy` redirect Node HTTP-adapter traffic through an attacker-controlled proxy.
CVE-2026-67324: GitPython 3.1.50 lets `-u` clone options escape the unsafe-option gate
A newly published August 2026 PyPI vulnerability shows GitPython 3.1.50 can still pass attacker-controlled helper commands to `git clone` through joined short options such as `-u<helper>`, turning clone wrappers that trust `allow_unsafe_options=False` into command-execution surfaces.
CVE-2026-53264: Linux net/sched `tc_action` race turns local filter access into root
The late-July 2026 public exploit write-up for `CVE-2026-53264` matters to AppSec teams because concurrent `RTM_NEWTFILTER` and `RTM_DELTFILTER` operations can reclaim a freed `tc_action` in `net/sched`, pivot `tcf_action_fill_size()` through a forged vtable, and turn ordinary local code execution on user-namespace-enabled Linux hosts into init-namespace root until fixed kernels such as `5.10.259`, `5.15.210`, `6.1.176`, `6.6.143`, `6.12.94`, `6.18.36`, or `7.0.13` are deployed.
Joyfill beta npm releases turned module import into a blockchain-resolved RAT chain
Late-July 2026 research shows malicious Joyfill prereleases appending an import-time loader to built bundles, exporting `require` and `module` into globals, resolving second-stage code through Tron, Aptos, and BNB Smart Chain transactions, and then pivoting into a Socket.IO RAT plus developer-tool persistence.
Alibaba-targeted npm cluster split a RAT loader across 18 packages and a live GitHub rule file
Fresh July 28 research ties 18 npm package names impersonating Alibaba-internal tooling to a distributed loader chain. Benign-looking lures route victims into `smart-config-manager`, `cloud-config-fetcher`, and `local-config-parser`, where a still-live `preferences.json` rule uses `items.constructor.constructor` to escape into Node.js process scope and fetch `setting.js` from Alibaba Cloud.
Weekly Briefing - 28-07-2026
Corgea's weekly briefing for 22-28 July 2026 covers GitHub Actions abuse tied to cPanel/WHM exploitation, ViteVenom's blockchain-backed npm RAT, RefluXFS's XFS local-root race, and Netty's July decoder DoS fixes.
CVE-2026-64600: RefluXFS turns XFS reflink races into Linux root
Qualys' July 2026 RefluXFS disclosure matters to AppSec teams because a stale XFS data-fork mapping after an `ILOCK` cycle lets ordinary local code execution redirect `O_DIRECT` writes into root-owned files on reflink-enabled volumes, with public metadata tracking affected Linux kernels back to 4.11 and fixes in upstream stable lines such as 6.12.96, 6.18.39, and 7.1.4.
CVE-2026-44891, 55831, and 55833: Netty 4.1.136 / 4.2.16 patch STOMP and SPDY DoS primitives
Newly published July 2026 Netty advisories matter to Maven teams because `io.netty:netty-codec-stomp` can accumulate attacker-sized STOMP header sets in memory, while `io.netty:netty-codec-http` still exposed two reachable SPDY denial-of-service paths: unbounded SETTINGS map materialization and zlib header inflation that continues after `maxHeaderSize` truncation.
GitHub Actions abuse turned ten Packagist dev packages into a Linux scanner for cPanel/WHM CVE-2026-41940
Socket's July 22 research shows that compromised `dinushchathurya/*` Packagist development versions were only the visible edge of a broader GitHub Actions campaign: 583 malicious workflow files used GitHub-hosted Ubuntu runners to fetch Linux payloads from `43[.]228[.]157[.]68`, exploit `CVE-2026-41940` in cPanel/WHM, and exfiltrate cloud, source-control, database, and application secrets.
ViteVenom: seven fake Vite npm scopes used blockchain dead-drops to launch a detached RAT
New July 2026 research on the ViteVenom cluster shows seven malicious npm packages impersonating Vite-related tooling, hiding their loader in `bin/vite.js`, resolving second-stage payloads through Tron, Aptos, and Binance Smart Chain transactions, and spawning a detached Node process that survives the original package execution.
Weekly Briefing - 21-07-2026
Corgea's weekly briefing for 15-21 July 2026 covers SleeperGem's dormant RubyGems maintainer compromise, Pepesoft's malicious NuGet tool cluster, and CVE-2026-48815 in sigstore-js.
SleeperGem: hijacked dormant RubyGems accounts turned `require` into a persistent developer backdoor
Between 18 and 19 July 2026, attackers used dormant RubyGems maintainer accounts and a brand-new `git_credential_manager` gem to push a staged loader chain into `Dendreo` and `fastlane-plugin-run_tests_firebase_testlab`. The malicious Ruby code disabled TLS verification, fetched shell or PowerShell payloads from a public Forgejo host, then escalated in `2.8.2` and `2.8.3` from an install-time dropper into a require-time path that planted a persistent daemon under `~/.local/share/gcm/`.
CVE-2026-48815: `sigstore-js` dropped `certificateOIDs` checks, weakening JavaScript artifact-verification policy
Newly cataloged this week, `sigstore` for npm accepted a documented `certificateOIDs` verification policy but silently discarded it before enforcement. Any JavaScript verification gate that relied on OID-bound signer identity in `sigstore <= 4.1.0` could accept signatures from certificates that should have failed policy.
11 malicious NuGet tools disguised as game cheats stage `pepesoft.exe` and spreadsheet-backed host surveillance
New 14 July 2026 research links 11 malicious `DotnetTool` NuGet packages to a shared downloader that resolves GitHub over DNS-over-HTTPS, stages `pepesoft.exe` from GitHub Releases or Hugging Face, injects cloud configuration through environment variables, and turns Google Sheets plus Telegram into operator telemetry, licensing, and screenshot-control channels.
AsyncAPI's July 14 npm compromise chained `pull_request_target`, unsigned branch pushes, and require-time malware
On 14 July 2026, attackers used a `pull_request_target` workflow in `asyncapi/generator` to steal a privileged token, pushed unsigned commits to AsyncAPI release branches, and published five malicious `@asyncapi` package versions whose payload fired on `require()`, pulled stage two from IPFS, and persisted as `NodeJS/sync.js`.
Weekly Briefing - 14-07-2026
Corgea's weekly briefing for 8-14 July 2026 covers Jscrambler's import-time npm compromise, Braintree.Net's production payment skimmer, Injective's wallet-key exfiltration release, and the week's most important Airflow, Paysafe, Operation Muck and Load, and apko/melange research.
CVE-2026-54174: `apko` and `melange` trusted APK control metadata without proving the installed data section
A newly published July 2026 advisory for `chainguard.dev/apko` and `chainguard.dev/melange` shows that builds before `apko` `1.2.9` and `melange` `0.50.4` verified the signed APK control section but not the package data section, letting a compromised mirror, poisoned cache, or MITM substitute the files actually installed into an OCI image while earlier integrity checks still passed.
Compromised `jscrambler` npm releases escalated from preinstall dropper to import-time Rust infostealer
On 11 July 2026, five malicious `jscrambler` npm releases (`8.14.0`, `8.16.0`, `8.17.0`, `8.18.0`, and `8.20.0`) shipped a cross-platform Rust infostealer that first executed through `preinstall`, then pivoted into `dist/index.js` and the CLI entrypoint to survive `--ignore-scripts` and hook-only scanning.
Braintree.Net on NuGet skims live card data, merchant keys, and host secrets in production
New July 2026 research exposed `Braintree.Net` as a NuGet typosquat of PayPal Braintree's official .NET SDK. The package hooks `CreditCardGateway` and `BraintreeGateway.PrivateKey`, siphons PAN/CVV and merchant credentials to `api.348672-shakepay[.]com`, and uses a companion `DependencyInjector.Core` package to auto-run environment and config harvesting through .NET module initializers.
Injective's 1.20.21 npm release turned wallet key derivation into mnemonic and private-key exfiltration
A compromised GitHub maintainer path pushed `@injectivelabs/sdk-ts@1.20.21` and 17 pinned companion packages to npm on 8 July 2026. The malicious release hooks `PrivateKey.fromMnemonic()` and `PrivateKey.fromHex()`, batches wallet secrets into an `X-Request-Id` header, and quietly POSTs them to an Injective-branded endpoint that blends into normal SDK traffic.
Malicious Go command module stages PowerShell loader and links to a 222-repository GitHub lure network
Socket's 8 July 2026 Operation Muck and Load research exposed a fake Go `dnsub` scanner, `github.com/kaleidora/dnsub-scanning-tool`, that launches hidden PowerShell staging on Windows and ties into a larger 222-repository GitHub lure network spanning 190 accounts.
CVE-2026-33264: Apache Airflow let DAG authors cross into scheduler and API-server RCE
Apache Airflow before `3.3.0` deserialized attacker-controlled trigger state while loading serialized DAGs on the Scheduler and API Server. That path reached `BaseSerialization.deserialize()`, which can `import_string()` attacker-chosen class paths, turning lower-trust DAG author input into higher-trust code execution across Airflow's control-plane processes.
Paysafe, Skrill, and Neteller typosquats on npm and PyPI stole developer secrets
A July 7 cluster of 17 malicious npm and PyPI packages impersonated Paysafe, Skrill, and Neteller integrations. The npm variants exposed a fake `PaysafeClient`, delayed exfiltration until SDK methods were called, decoded an ngrok-backed C2 at runtime, and harvested any environment variable that looked like a key, token, password, secret, auth value, or API credential.
CVE-2026-53359: Januscape turns KVM shadow-page role confusion into Linux guest-to-host escape
Januscape is a Linux KVM/x86 use-after-free where `kvm_mmu_get_child_sp()` reused shadow pages on GFN match alone, letting a nested guest trigger role confusion, orphaned rmap state, host kernel memory corruption, and guest-to-host compromise on affected Intel and AMD virtualization hosts.
Weekly Briefing - 07-07-2026
Corgea's weekly briefing for 1-7 July 2026 covers PolinRider's cross-ecosystem supply-chain expansion, the Rollup polyfill npm RAT chain, Bad Epoll's public Linux root exploit, and the week's most important TeamPCP, Keras, buffa/connectrpc, and libzypp research.
Rollup polyfill lookalikes on npm hide an import-time loader, JSONKeeper stage, and 216.126.236.244 RAT
A June 30-July 4 disclosure chain exposed six malicious npm packages impersonating `rollup-plugin-polyfill-node`. The backdoor lives in CommonJS `dist/index.js`, silently `npm install`s second-stage packages on `require()`, `eval`s JSONKeeper-hosted code, decrypts a follow-on payload from `216.126.236.244`, and turns developer workstations or CI runners into remote-access, browser-theft, clipboard-monitoring footholds.
CVE-2026-46242: Bad Epoll turns Linux eventpoll cleanup into local root
Bad Epoll is a Linux kernel race-condition use-after-free in eventpoll where concurrent close paths can corrupt freed kernel objects, turn `/proc/self/fdinfo` into a kernel-memory read primitive, and escalate ordinary local code execution to root on affected kernels.
FBI TeamPCP alert ties Trivy, KICS, LiteLLM, and Telnyx into one supply-chain playbook
July 2026 FBI-linked reporting consolidates TeamPCP's developer-tool tradecraft across Trivy, KICS, LiteLLM, Telnyx, npm, and PyPI: mutable CI artifacts, stolen registry credentials, Python startup hooks, runner-memory scraping, and GitHub dead-drop exfiltration.
CVE-2026-12481: Keras Lambda.from_config() turns unset safe mode into code execution
A July 3 PyPI disclosure shows that Keras 3.14.x can treat `safe_mode=None` as effectively disabled during `Lambda` layer deserialization, letting attacker-controlled marshaled bytecode reach `func_load()` and become executable Python functions.
PolinRider expands from npm into Go, Packagist, and Chrome extension supply-chain poisoning
July 2026 research shows the PolinRider campaign reusing off-screen JavaScript loaders, VS Code task abuse, blockchain dead-drop staging, and Git-history rewrite tradecraft across 162 malicious artifacts spanning npm, Go modules, Packagist, and a Chrome extension.
CVE-2026-25707: `libzypp` lets hostile repository metadata escape the cache root
A late-June Linux package-manager disclosure shows that pre-17.38.10 `libzypp` trusted `../`-style repository metadata locations, allowing a hostile or compromised repo to steer mirrored files outside the intended cache directory during refresh and making repository trust an arbitrary local file overwrite boundary.
CVE-2026-55407: `buffa` and `connectrpc` amplify tiny protobuf payloads into Rust OOMs
A June 30 disclosure shows that pre-0.8.0 versions of the Rust crates `buffa` and `connectrpc` can inflate streams of unknown protobuf fields into outsized heap allocations, turning small untrusted messages into process-killing memory amplification.
CVE-2026-58302: LinuxCNC rtapi_app path traversal to root
LinuxCNC before 2.9.9 installs rtapi_app with elevated privileges and feeds user-controlled module names into dlopen() after formatting ${EMC2_RTLIB_DIR}/${name}.so. Without rejecting slashes or .. segments, an unprivileged local user can traverse out of the module directory and load an arbitrary shared library as root.
Weekly Briefing - 30-06-2026
Corgea's weekly briefing for 24-30 June 2026 covers the ImmobiliareLabs Backstage plugin compromise, Leo Platform's expanding Phantom Gyp/Miasma package wave, expr-eval's no-fix Node.js code-execution flaw, and Vite's Windows dev-server secret leak.
CVE-2026-13502: antlr4-maven-plugin build-state deserialization
CVE-2026-13502 affects org.antlr:antlr4-maven-plugin 4.13.0 through 4.13.2. The public disclosure frames it as a race around the plugin's dependency-status file, but the practical sink is unfiltered ObjectInputStream deserialization of build-directory state under target/maven-status/antlr4/dependencies.ser.
ImmobiliareLabs Backstage plugins compromised with Phantom Gyp Miasma payload
On 26 June 2026, 22 malicious patch releases hit four `@immobiliarelabs` Backstage plugin families. The poisoned npm artifacts added a `binding.gyp` trigger plus a new 5 MB root `index.js`, turning `npm install` into install-time code execution against environments that often hold GitLab, LDAP, CI, cloud, and developer-portal secrets.
CVE-2026-53571: Vite `server.fs.deny` bypass leaks protected files on Windows
Vite's dev server on Windows can leak `.env`, `.env.*`, and certificate files that developers expected `server.fs.deny` to block. The bypass uses NTFS alternate-data-stream path forms such as `/.env::$DATA?raw` and, in some cases, 8.3 short-name aliases, affecting `vite` before `6.4.3`, `7.3.5`, and `8.0.16` when the dev server is exposed beyond localhost and the target file sits in an allowed directory.
Leo Platform npm packages compromised with Phantom Gyp Miasma toolkit
On 24 June 2026, malicious versions of 23 Leo Platform npm packages were published in a six-second burst. Follow-up reporting on 25 June shows the wave was broader than the initial 20-package view: three additional prerelease connector packages were poisoned, `leo-sdk`'s `latest` dist-tag was redirected to the malicious `6.0.19` line, and the same Phantom Gyp plus Bun-staged payload family also overlapped with adjacent npm and source-repository poisoning activity.
CVE-2026-12866: `expr-eval` turns untrusted formulas into Node.js code execution
A newly published June 2026 npm vulnerability shows that every `expr-eval` release can compile attacker-influenced formulas into executable JavaScript through `Expression.prototype.toJSFunction()`, exposing Node.js services, internal tools, and CI helpers that treat user formulas as data.
Weekly Briefing - 23-06-2026
Corgea's weekly briefing for 17-23 June 2026 covers the Mastra npm scope takeover that weaponized easy-day-js across more than 140 packages, plus Nodemailer's newly disclosed raw-message file-read and SSRF bypass.
Nodemailer raw option bypasses disableFileAccess and disableUrlAccess
A newly published high-severity Nodemailer advisory shows that every version up to 9.0.0 can turn attacker-controlled `raw` message input into arbitrary local-file disclosure and full-response SSRF, because the `MailComposer` raw-message path drops the `disableFileAccess` and `disableUrlAccess` guards before `MimeNode` resolves `{ path }` or `{ href }` content.
Mastra npm scope takeover used easy-day-js to Trojanize 141-143 packages
On 17 June 2026, a compromised Mastra maintainer account republished 141 `@mastra/*` packages plus the top-level `mastra` and `create-mastra` packages with a new `easy-day-js: ^1.11.21` dependency that resolved to a weaponized `1.11.22` postinstall dropper, turning fresh npm installs into a detached second stage that established cross-platform persistence, profiled browsers and wallets, and, in Microsoft's 19 June follow-up, was tied to Sapphire Sleet activity that escalated some Windows hosts into PowerShell-backed, SYSTEM-level persistence.
GlassWASM used TinyGo WebAssembly and Solana memos in trojanized Open VSX extensions
Trojanized Open VSX copies of `ExarGD.vsblack@0.0.1` and `noellee-doc.flint-debug@0.1.1` cloned legitimate extension identities, auto-executed a TinyGo-compiled WebAssembly payload on startup, polled Solana JSON-RPC for memo-based command-and-control, and built OS-specific `child_process` download-and-execute commands for macOS, Linux, and Windows.
Weekly Briefing - 16-06-2026
Corgea's weekly briefing for 10-16 June 2026 covers the uncovered remainder of the week's research: the dbmux Phantom Gyp / Miasma compromise, Dulwich's Windows and format-patch path traversal fixes, libp2p's unauthenticated DHT disk-exhaustion flaw, and Spring's internally discovered WebFlux and static-resource DoS fixes.
CVE-2026-50010, 50011, 50020, and 50560: Netty 4.1.135 / 4.2.15 fix TLS, HTTP/1.1, HTTP/2, and Redis parser flaws
Netty's June security train matters to Maven teams because a custom trust manager can silently disable HTTPS hostname verification, `HttpObjectDecoder` can over-accept leading control bytes and enable request-boundary confusion, `RedisArrayAggregator` can allocate attacker-sized arrays, and HTTP/2 servers can be coerced into response-write failures via client-advertised header limits.
Weekly Briefing - 15-06-2026
Corgea's weekly briefing for 10-15 June 2026 covers the Atomic Arch AUR takeover, Netty's security-heavy 4.1.135 / 4.2.15 release, the onering crates compromise, and a late-breaking Open VSX extension attack that used TinyGo WebAssembly plus Solana memo-based C2.
Atomic Arch turned orphaned AUR packages into npm and Bun malware launchers
The June 11-12 Atomic Arch campaign adopted orphaned AUR packages, inserted `npm install atomic-lockfile` or Bun-based `js-digest` / `lockfile-js` fetches into package hooks, and used a malicious lifecycle script to execute `src/hooks/deps`, a Linux ELF infostealer with optional eBPF hiding logic across a verified `1,619` unique AUR package names.
CVE-2026-42305 and CVE-2026-47712: Dulwich 1.2.5 fixes Windows checkout abuse and format_patch path traversal
Dulwich before 1.2.5 accepts NTFS-hostile tree entries that can plant files under .git or escape the work tree on Windows, and it also derives format_patch filenames from unsanitized commit subjects, letting attacker-controlled commits write patch files outside the requested output directory.
CVE-2026-45783: @libp2p/kad-dht lets unauthenticated peers fill disk with unvalidated PUT_VALUE records
A newly published flaw in @libp2p/kad-dht before 16.2.6 allows any remote peer to stream crafted PUT_VALUE messages whose keys bypass record validation, turning DHT server nodes into unbounded disk sinks until the host or container runs out of storage.
CVE-2026-41840 and CVE-2026-41842: Spring 7.0.8 fixes WebFlux multipart and versioned-resource DoS flaws
Spring Framework 7.0.8 and 6.2.19 fix two newly disclosed denial-of-service flaws that matter to Maven-based application teams: a WebFlux multipart-processing leak reachable through hostile multipart bodies, and a static-resource resolution path that can pin connections when versioned filesystem assets are enabled.
dbmux npm package used Phantom Gyp to execute Miasma during install
The `dbmux` npm package was classified as critical malware after public tracking tied compromised `1.x` and `2.2.x` releases to Miasma's Phantom Gyp technique, where a weaponized `binding.gyp` forces `node-gyp rebuild` to execute a hidden loader during `npm install` even when `package.json` does not advertise lifecycle scripts.
onering 1.4.1 used Cargo build.rs to exfiltrate private source diffs
The compromised Rust crate `onering@1.4.1` added a 74-line `build.rs` that walks out of Cargo's `OUT_DIR`, runs `git log -n 1` and `git diff HEAD^ HEAD` against the consuming repository, and posts commit metadata plus the latest source diff to a Sentry ingest endpoint on every build.
Hades PyPI follow-on hit MCP packages and Python typosquats
On June 9, 2026, the Hades PyPI campaign expanded beyond the earlier scientific-package wave into MCP tooling and typo-squatted Python packages such as `openai-mcp`, `langchain-core-mcp`, `instructor-mcp`, `tiktoken-mcp`, `ray-mcp-server`, `rsquests`, `rlask`, and `tlask`, using `.pth` loaders, split staging, and native-extension triggers to launch a Bun-executed stealer.
Weekly Briefing - 09-06-2026
Corgea's weekly briefing for 2-9 June 2026 covers the Phantom Gyp Miasma npm wave, Hades' expansion into MCP-focused PyPI packages, the nvm mirror command injection flaw, and the now-exploited Oracle WebLogic T3/IIOP exposure issue.
CVE-2026-10796 lets hostile mirrors turn `nvm install` into shell RCE
A June 4 disclosure showed that nvm <= 0.40.4 trusted version fields from mirror index.tab metadata, letting hostile or MITM'd mirrors inject commands into both nvm_download() and nvm_get_checksum(). Version 0.40.5 fixes the issue by removing eval from downloader execution, passing tarball names to awk as data, and rejecting disallowed characters in mirror-supplied version strings.
CVE-2026-44488: Axios fetch adapter bypasses maxContentLength and maxBodyLength
Axios 1.7.0 through 1.15.x does not enforce configured request and response size limits when the fetch adapter is selected, allowing oversized uploads, downloads, and data: URL bodies to exhaust memory and CPU on server-side runtimes that relied on those limits as a security boundary.
Phantom Gyp Miasma hit Vapi, ai-sdk-ollama, and 55 more npm packages
A June 3-4 Miasma follow-on wave used a 157-byte binding.gyp file to force node-gyp command substitution during npm install, turning @vapi-ai/server-sdk, ai-sdk-ollama, and dozens of autotel, awaitly, executable-stories, and node-env-resolver packages into Bun-staged credential-stealing worm loaders while leaving their real dist/ code untouched.
CVE-2024-21182: Oracle WebLogic T3 and IIOP exposure is now exploited
CISA added CVE-2024-21182 to KEV after active exploitation of an Oracle WebLogic Server Core flaw that is reachable without authentication over T3 and IIOP and can expose all WebLogic-accessible data.
Miasma poisoned Red Hat Cloud Services npm packages through trusted publishing
A compromised Red Hat GitHub account pushed orphan commits into RedHatInsights repositories and used GitHub Actions OIDC trusted publishing to ship Miasma, a Bun-staged credential-stealing worm with GitHub dead-drop exfiltration and local persistence, across @redhat-cloud-services npm packages.
Weekly Briefing - 02-06-2026
Corgea's weekly briefing for 26 May-2 June 2026 covers the Red Hat Cloud Services Miasma npm compromise, private Gitea and Forgejo container-image exposure, the js-logger-pack MicrosoftSystem64 implant, banking-certificate theft through a malicious NuGet SDK, dependency-confusion reconnaissance, OpenSearch npm typosquats, CMS privilege escalations, and stored editor XSS.
CIFSwitch turns Linux CIFS SPNEGO upcalls into local root
CIFSwitch is a Linux kernel and cifs-utils privilege escalation where an unprivileged process can forge a cifs.spnego key request, make request-key launch cifs.upcall as root, and force NSS code execution inside an attacker-controlled namespace.
CVE-2026-27771 exposed private Gitea and Forgejo container images
CVE-2026-27771 is a Gitea container registry authorization flaw where unauthenticated requests could pull private OCI image manifests and layers from affected self-hosted instances, exposing application code, dependencies, and secrets baked into images.
roberts/leads Packagist dev branch hid a Famous Chollima blockchain loader
The Packagist package roberts/leads exposed a poisoned development branch as dev-drewroberts/feature/test-case, where tailwind.js appended obfuscated JavaScript that resolved payload material through TRON, Aptos, and BNB Smart Chain before executing it in Node.js.
oob.moika.tech npm campaign used dependency confusion to profile developer environments
Public reporting tied at least 179 malicious npm package-version records to an oob.moika.tech dependency-confusion campaign that abused internal-looking scopes, postinstall hooks, inflated versions, and detached JavaScript payloads to inventory developer and CI environments.
