Use when auditing OAuth 2.0 / OIDC implementations against RFC 9700 (OAuth Security BCP), reviewing client or authorization-server code, evaluating PKCE / state / redirect-URI handling, hardening token exchange and refresh flows, or triaging suspected OAuth vulnerabilities (CWE-352 CSRF, CWE-287 broken auth).
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# OAuth 2.0 / OIDC Security Audit Formal review workflow for OAuth 2.0 and OpenID Connect implementations. Maps every finding to a normative source (RFC 9700 §, OWASP, CWE) and produces a severity-rated report — not a generic "best practices" summary. ## Quick Reference | What | Details | |------|---------| | **Primary spec** | [RFC 9700](https://www.rfc-editor.org/rfc/rfc9700.txt) — OAuth 2.0 Security Best Current Practice (Jan 2025) | | **Adjacent specs** | RFC 6749 (core), RFC 6750 (bearer), RFC 7636 (PKCE), RFC 9207 (`iss` mix-up), RFC 8414 (AS metadata), RFC 7009 (revocation) | | **OWASP** | A07:2025 Authentication Failures, A01:2025 Broken Access Control | | **CWE** | CWE-352 (CSRF), CWE-287 (broken auth), CWE-601 (open redirect), CWE-384 (session fixation) | | **Deprecated grants** | Implicit (`response_type=token`), Resource Owner Password Credentials | | **Always required for public clients** | PKCE with `S256` (never `plain`) | | **Mix-up defence** | RFC 9207 `iss` parameter or per-AS distinct redirect URIs | ## When to Use - Reviewing an OAuth/OIDC client integration (login-with-Google/GitHub/Azure, mobile, SPA, CLI) …

How to install
mdr add lu1sdv/skillsmd/oauth-audit@sha256:08643c29bbe78071The line at the top of this page pins the label git:20260429.7c58be2, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
