What StackAudit detects in sub-seconds

Three core detection pillars running in parallel across AST call graphs, lockfiles, and PR diffs.

1. Critical CVEs & Vulnerabilities

Detects taint injection flows, secret leaks, and known exploit vectors with automated remediation paths.

authService.ts
[OWASP A03]
// Taint sink: raw user string injection
const token = req.query.token;
// [CRITICAL RISK] Unparameterized SQL Query
db.query(`SELECT * FROM users WHERE token = '${token}'`);
→ Fix: db.query('SELECT * FROM users WHERE token = $1', [token]);

2. Code Smells & Tech Debt

AST complexity analysis, cyclomatic depth limits, memory leak hazards, and anti-pattern refactoring roadmaps.

useWebSocket.ts
[GRADE A]
// Cyclomatic Index: 1 • Maintainability: 94/100
useEffect(() => {
const socket = new WebSocket(url);
socket.onmessage = (e) => setData(e.data);
// [RESOLVED] Teardown listener on unmount
return () => socket.close();
}, [url]);

3. Risky Open-Source Dependencies

Fast lockfile audit resolving known CVEs via Google OSV API and SPDX copyleft license liabilities.

[HIGH RISK] [email protected] → CVE-2020-28168
• Severity: SSRF URL schema bypass
// [ACTION REQUIRED] SPDX Conflict: AGPL-3.0 detected
→ Fix: Upgrade axios to >= 0.21.4 (Auto-Fix PR Ready)
