Actionable writeups with exploit context, metadata, and practical remediation details.
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.
