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Go/Dart: go list -m -u all | dart pub outdated --json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.
