Review security

Skill gabriel-f-santos/coding-agents/skills/review-security

Security review of changed code, scoped to a phase/feature diff. Use to find exploitable vulnerabilities in what was just built — "revisa segurança da fase", "tem vuln nessa feature?", "security review do diff", "checa injection/authz/IDOR". Reports HIGH-confidence, attacker-reachable issues only (injection, broken authZ / cross-tenant / IDOR, secret exposure, missing validation, SSRF, deserialization, crypto misuse) AND supply-chain gaps (unpinned deps / uncommitted lockfile / no cooldown). Read-only — reports, does not fix. Runs standalone or as a subagent of review-phase. Do not use for functional conformance (review-functionality) or style/cleanup (review-quality).From its SKILL.md

2 things to look at

  • no licenseNo license file was found in the repository. Code published without one is not open source by default, so using it at work is a question for whoever answers licensing questions where you are.
  • 0 stars0 stars. Stars are a popularity signal and not a quality one, but at this level it is likely that nobody has read this closely except its author, and you would be relying on your own review.

review-security — exploitable issues in the changed code

Find HIGH-confidence, attacker-reachable vulnerabilities in the diff. Research the whole repo to build confidence (where does this input come from? is there validation elsewhere?), but report only on the changed code. Investigate first, then report — don't flag on pattern match alone.

Inputs

The change set (files/diff) and, when run by review-phase, the phase contract excerpt (helps spot missing auth/validation a criterion implied).

What to check (report only what's exploitable)

  • Injection — SQL/NoSQL/command/template/LDAP: attacker-controlled input concatenated into a query/command/path without parameterization or escaping.
  • AuthN/AuthZ — missing/incorrect authentication; broken authorization: an action not checked against the caller's rights. For multi-tenant: cross-tenant / IDOR — reading or writing another tenant's data by changing an ID; trusting a tenant/user id from the request body instead of the resolved session.
  • Secret exposure — hardcoded keys/tokens/passwords; secrets logged or returned in responses.
  • Input validation — unvalidated/oversized input reaching a sink; mass-assignment.
  • SSRF — server-side request to an attacker-controlled URL.
  • Deserialization / file handling — unsafe deserialization; path traversal; unrestricted upload.
  • Crypto — weak/again-static IV, predictable tokens, missing TLS expectation, plaintext storage of sensitive data.
  • Supply chain (dependencies) — a dep installed without an effective version lock is a 2026 vulnerability: missing/uncommitted lockfile, install that ignores it (npm install vs npm ci), unbounded ranges (*/latest/>= no ceiling, no lock), and no cooldown (minimumReleaseAge / Dependabot cooldown) so an update can pull a just-published malicious version. When the diff adds/bumps a dependency, check it. → references/supply-chain.md

Do NOT flag

  • Test files, dead/commented code, docs.
  • Server-controlled values (config/env/constants) treated as attacker input.
  • Pure best-practice/defense-in-depth with no attacker path (note at most as MEDIUM).
  • Anything that requires prior trusted access not reachable from the change.

Confidence & output

HIGH = vulnerable pattern + attacker-controlled input confirmed → report. MEDIUM = pattern present, source unclear → "needs verification". LOW = theoretical → drop. Return: {dimension: security, severity, confidence, file:line, issue, evidence, attack (how it's reached), why_it_matters, fix}. False-positive discipline matters more than coverage — a noisy security review gets ignored.
