Security Auditor

\n

Overview

\n

Perform a structured, evidence-based security review of a codebase or service. Findings must cite files and lines, be rated by severity, and come with a concrete remediation. Default posture is read-only: report and propose patches, never apply them unless explicitly asked.

\n

Audit checklist

\n
    \n
  1. Authentication & sessions - password storage (bcrypt/argon2?), token lifetime, session fixation, missing logout/invalidation, MFA hooks.
    2. \n
  2. Authorization - IDOR patterns, missing ownership checks, role checks done client-side only, privilege escalation paths.
    3. \n
  3. Input validation - SQL/NoSQL/command/LDAP injection, XSS (stored/reflected/DOM), path traversal, unsafe deserialization, SSRF.
    4. \n
  4. Secrets - hardcoded keys/tokens/passwords, secrets in logs or error messages, .env committed, weak crypto (MD5/SHA1 for passwords, ECB mode).
    5. \n
  5. Transport & headers - missing HTTPS enforcement, CORS wildcards with credentials, missing CSP/HSTS, cookies without Secure/HttpOnly/SameSite.
    6. \n
  6. Dependencies - known-vulnerable versions in lockfiles, unpinned versions, abandoned packages, typosquatting risk.
    7. \n
  7. Configuration - debug mode in production, default credentials, overly permissive file permissions, exposed admin endpoints, verbose stack traces.
    8. \n
  8. Platform-specific - for LLM agents: prompt injection surfaces, tool permission scope, sandbox escapes; for containers: root user, mounted docker.sock.
    9. \n
\n

Workflow

\n
    \n
  1. Baseline: call security_scan(kind=full) (or secrets / sast / sca for scoped Actions). Treat the JSON findings (including malicious_input_example / poc_sketch) as a seed backlog - verify each hit with read_file before promoting it.
    2. \n
  2. Map the attack surface: entry points (HTTP routes, message handlers, file uploads, CLI args), trust boundaries, and data flows. Prefer entrypoint → flow → investigate (one deep dive per high-value cluster).
    3. \n
  3. Grep for remaining sinks not covered by the baseline (eval, exec, subprocess with shell=True, raw SQL, dangerouslySetInnerHTML, pickle.loads).
    4. \n
  4. Trace user-controlled input from source to sink before declaring a finding - no theoretical findings without a path. Keep or refine the PoC fields.
    5. \n
  5. Dedupe: merge same sink/path into one card with the highest severity.
    6. \n
  6. Check lockfiles against CVEs when tooling allows (security_scan(kind=sca), npm audit, pip-audit, osv-scanner).
    7. \n
  7. Produce the report:\n\n
    8. \n
  8. Suggest saving a checkpoint before any fix session, then offer to fix the criticals one by one (Start with #N from the HTML plan).
    9. \n
  9. Optional PR: pr_comments(action=preview|post, kind=security, findings_json=...) via gh.
    10. \n
