Systematically reviews code for SQL injection, XSS, SSRF, broken access control, cryptographic failures, and other common OWASP Top 10 vulnerabilities, providing vulnerable code examples and ready-to-use remediation guidance. Trigger this skill when users ask for a security review, vulnerability scan, or penetration testing assistance, or mention keywords like OWASP, SQL injection, XSS, code audit, or security checklist.
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
# OWASP Top 10 Code Security Review Checklist A systematic security review based on the OWASP Top 10 (2021) standard. Each item includes: vulnerability description, typical vulnerable code, inspection checkpoints, and remediation examples. Designed for security-focused code review of web applications. ## Usage Provide the code files or code snippets to review, and specify which OWASP categories to check (or request a full review) to receive an item-by-item audit report. **Example prompts:** - "Check this code for SQL injection risks" - "Run a full OWASP Top 10 security review on this project" - "Does this API endpoint have any SSRF vulnerabilities?" --- ## Quick Reference | ID | Category | Key Check | |----|----------|-----------| | A01 | Broken Access Control | Does every endpoint verify the current user's identity? Can users access others' data by changing IDs? | | A02 | Cryptographic Failures | Are passwords hashed with bcrypt/argon2? Are secrets hardcoded? | | A03 | Injection | String-concatenated SQL? `shell=True`? Unescaped template output? | | A04 | Insecure Design | Is rate limiting in place? Can critical workflows be bypassed? | …

How to install
mdr add zebbern/claude-code-guide/secure-code-review@sha256:d3c9fac00e49454bThe line at the top of this page pins the label git:20260531.164971d, 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.
