One extension, two threat models
A .ts file may render in the browser or run with database credentials. Scanners that treat both the same flood you with irrelevant findings.
For JavaScript & TypeScript teams
A JavaScript security scanner that knows frontend from backend
Corgea classifies every JS and TS file as browser or server code before scanning, so React components get DOM XSS rules and Express routes get injection and authorization analysis, with review-ready fixes in the PR.

Pain points
Why JavaScript is hard to scan well
The challenges teams hit before they bring Corgea into their workflow.
Pattern matching misses the missing check
IDOR, mass assignment, and skipped authorization are absent lines, not dangerous ones, so grep-style rules never see them.
Full-stack frameworks blur the line
Next.js server actions, route handlers, and middleware sit next to client components, and secrets slip into bundles through NEXT_PUBLIC_ prefixes.
npm noise drowns out real risk
Hundreds of transitive packages generate advisories that are never reachable, while typosquats and malicious install scripts slip through.
How Corgea helps
How Corgea scans JavaScript and TypeScript
Context-aware static analysis for the browser, Node.js, and everything in between.
Frontend and backend detection
Framework signatures, imports, and code patterns route each file to the right ruleset: DOM XSS, open redirects, and postMessage abuse for the browser; SQL and command injection, path traversal, SSRF, and auth bypass for the server.
Business logic and authorization flaws
Corgea understands what a route is supposed to do, so it flags the missing ownership check and the unsafe merge, not just the dangerous innerHTML.
Fixes developers can merge
Every finding ships with a review-ready fix and a plain-English explanation, delivered in the pull request, the IDE, or through MCP to your coding agent.

Outcomes
What JavaScript teams get with Corgea
- Fewer false positives because React auto-escaping and server context are understood.
- Coverage for XSS, injection, prototype pollution, SSRF, and broken authorization in one scan.
- Findings and fixes in the pull request before merge, not in a separate dashboard.
- Dependency risk prioritized by real usage alongside first-party code findings.
FAQ
JavaScript & TypeScript questions teams ask before they buy
Short answers built for search visibility and faster evaluation.
Which JavaScript frameworks does Corgea support?
Corgea scans JavaScript and TypeScript across React, Next.js, Angular, Vue, Express, Fastify, NestJS, and plain Node.js, and supports more than 20 languages and frameworks overall.
What JavaScript vulnerabilities does Corgea detect?
Corgea detects DOM, stored, and reflected XSS, SQL and NoSQL injection, command injection, code injection through eval and template engines, prototype pollution, insecure deserialization, SSRF, path traversal, open redirects, insecure storage, and authorization and business logic flaws such as IDOR and mass assignment.
Does Corgea know the difference between frontend and backend JavaScript?
Yes. Before scanning, Corgea classifies each file as frontend or backend using framework signatures, import statements, and code patterns, then applies the matching ruleset so browser findings do not show up in server code and vice versa.
How does Corgea fit into a JavaScript CI pipeline?
Run the Corgea CLI or integration on every pull request to scan the diff, use blocking rules by severity and CWE to gate merges, and schedule full-repository scans for complete coverage. Findings and fixes appear as pull request comments.
