common-security-audit

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.

Security Audit

Priority: P0 (CRITICAL)

1. Scan for Hardcoded Secrets

See implementation examples for secrets scanning commands.

Covers: Backend source, frontend bundles (REACT_APP_, NEXT_PUBLIC_, VITE_), mobile configs (BuildConfig, iOS configurations, strings.xml).

2. Detect Data Leakage in Logs

See implementation examples for log leakage scanning commands across Node, Go, Dart, Java, Swift.

3. Map Injection Surfaces & Auth Coverage

See implementation examples for injection detection and auth coverage measurement.

4. Run Dependency CVE Scans

Node/Python/Rust: npm audit --audit-level=high | pip-audit | cargo audit
Go/Dart: go list -m -u all | dart pub outdated --json
Java/Mobile: mvn dependency:list / ./gradlew dependencies | pod audit / Gradle scan

5. Infrastructure & Adversarial Entry Points

See implementation examples for RCE/SSRF/Path Traversal and infrastructure hardening (Docker/K8s).

6. Frontend-Specific Audit

Exposed Secrets: grep -rE "(REACT_APP_|NEXT_PUBLIC_|VITE_)" . --include="*.ts*" --include="*.env*"
DOM Sinks & Source Maps: Check dangerouslySetInnerHTML, innerHTML, eval, and .map files in prod builds.

7. Mobile-Specific Audit

See mobile audit commands for insecure storage (credential stores/Keystore), cert pinning, debug flags, and deep links.

8. Business Logic & Advanced Attacks

BOLA/IDOR: Verify entity lookups always enforce tenant/owner ownership checks (e.g. any findById without an owner filter is a P0 IDOR vulnerability).
JWT / Mass Assignment: Check missing exp, weak keys, and uncontrolled property spread (...req.body).
Race / GraphQL: Verify atomic DB transactions, introspection disabled, and query depth limits.

Scoring Impact

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.

Anti-Patterns

No applying generic patterns over project-specific rules: Respect existing security constraints.
No ignoring error handling or edge cases: Audit must cover boundary conditions.
No backend-only audit: Always check frontend AND mobile when in-scope.
