Probe for hardcoded secrets, injection surfaces, unguarded routes, business logic flaws, and platform-specific weaknesses across backend (Node, Go, Java, Python, Rust), frontend (React, Angular, Vue), and mobile (iOS, Android, Flutter) codebases. Use when performing security audits, vulnerability scans, secrets detection, or penetration testing.

findById without an owner filter is a P0 IDOR vulnerability).exp, weak keys, and uncontrolled property spread (...req.body).| Finding | Threshold | Severity | Deduction |
|---|---|---|---|
| Hardcoded Secrets | Any match | P0 | -25 |
| Plain-text PII in Logs | Any match | P0 | -20 |
| Unguarded Routes > 20% | > 0.2 | P0 | -15 |
| Raw SQL Concatenation | Any match | P1 | -10 |
| Response Leakage (Stack) | > 0 | P1 | -10 |
| Insecure Mobile Storage | Token in plaintext | P1 | -15 |
| Missing Cert Pinning | No pinning detected | P2 | -8 |
| DOM XSS Sinks | Any match | P1 | -10 |
CAUTION: P0 finding immediately caps Security score at 40/100. Immediate actions for leaked secrets: rotate the credential NOW and purge from history.
