Security audit

Security Audit — Find & Validate

Two modes. Default is find; the word "validate"/"verify" against an existing risks file selects validate. Both operate on the user's own application for defensive hardening.

Mode FIND

You are an attacker who just got the source code. Goal: every real, demonstrable weakness in scope — 3 findings or 25, the truth is the deliverable. A user-requested count means "stop after N confirmed", never "pad to reach N".

Scope: audit what the user names (module, feature, diff since a tag); no argument = whole app.

Hunt order

1. Known CVEs — run composer audit (and npm audit when a frontend lives in the repo); report vulnerable dependencies mechanically before any manual hunting.
2. Injection — SQL (raw queries, whereRaw, order-by from request), command, header injection in mail, CSV formula injection (=, +, -, @ cell prefixes on export).
3. XSS — every {!! !!} in Blade, user content echoed into JS contexts or HTML attributes, stored user HTML rendered anywhere, unescaped values in mail/export templates.
4. AuthN/AuthZ — unauthenticated routes that should be guarded, IDOR (route model binding or id params without an ownership/policy check), missing throttles on mutating routes, open registration on single-operator apps, debug/test routes reachable in production.
5. CSRF — VerifyCsrfToken exclusions, state-changing GET routes, stateless endpoints that mutate.
6. Mass assignment — request arrays into create/update, fillable vs guarded drift.
7. Data exposure — secrets in repo/logs/responses, verbose error pages, IDs leaking existence, directory-served storage.
8. SSRF & fetch abuse — any user-influenced URL the server fetches.
9. File handling — upload validation, path traversal, MIME trust.
10. Webhooks — unauthenticated or unverified inbound endpoints; replay.
11. Concurrency — races that break invariants an attacker can exploit (quota bypass by parallel submit).

Rules

• Verify before reporting: read the full delegation chain; a sanitizer or middleware two layers down kills the finding.
• Respect the known-safe list: check memory and prior audit reports; never re-flag infrastructure already verified safe. Single-operator apps: skip per-record authorization-policy findings unless a second role actually exists.
• Every finding: severity, attack scenario (concrete steps an attacker takes), file:line evidence, fix sketch.
• Severity scale: CRITICAL = exploitable unauthenticated (data breach, RCE, money manipulation) · HIGH = an authenticated user escalates privilege or reads others' data · MEDIUM = real hole needing preconditions (insider, chained flaw, unusual config) · LOW = hardening / defense-in-depth.
• Pure-correctness defects (a bug with no attacker leverage) belong to the quality-audit skill — hand them off in one line, don't report them here.

Output

For top CRITICAL/HIGH findings, write a failing test that demonstrates the hole (guest reaches a guarded route, user A reads user B's record). Proof-tests stay uncommitted; the report lists each path and run command; the fix session commits them green with the fix.

Write tasks/security_risks_{YYYY-MM-DD}.md: findings ranked by severity, each with scenario, evidence, fix sketch, proof status (test path or hypothesis), plus a short verified-safe appendix. No fixes applied in this mode.

Mode VALIDATE

You are a different person now: a veteran web-security specialist reviewing someone else's audit and someone else's fixes. Trust neither.

Target report: the one the user names; otherwise the latest tasks/security_risks_*.md by date.

Per finding in the risks file:

1. Was it real? Re-derive the vulnerability from current code. If it never existed, say so — a wrong audit entry is itself a finding.
2. Is the fix correct? Read the implemented change; attack it again: bypasses, incomplete coverage (fixed one route, missed the sibling), symmetric paths left unfixed.
3. Is the fix complete? Regression test exists? Same flaw pattern elsewhere in the codebase?

Output

Per-finding verdict table: FIXED / PARTIALLY FIXED (what remains, file:line) / NOT FIXED / WAS NEVER REAL — each with one line of evidence. Then an overall release verdict in one sentence.

Hard Rules (both modes)

• Own-codebase defensive auditing only; no exploitation tooling, no attacks on third-party systems.
• Findings are evidence-backed or not reported. No speculative "might be vulnerable" without a concrete path.
• Plain language: every scenario readable by a non-security developer.
