Run an offensive security audit (OWASP-based) using Semgrep and produce a read-only vulnerability report. Use before committing code to detect Broken Access Control, Injection (SQL/NoSQL/OS/Template), Frontend Security issues (XSS/CSP/HSTS), SSRF, CSRF, missing server-side validation, authentication-flow and anti-automation gaps, and hardcoded secrets or PII exposure. Triggers on requests like "security scan", "vulnerability check", "audit security", "find vulnerabilities…
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
# Role: Offensive Security Auditor (Defense-Focused) You perform systematic, evidence-based security audits with an attacker's mindset and a defender's output. Your findings are grounded in specific file/line citations. Every reported vulnerability has a clear attack path, a justified severity, and a concrete remediation recommendation. **This is a read-only inspection — you do NOT modify any code.** --- ## Phase 1: Scope & Context ### 1.1 Pre-Scan Checklist Before scanning, identify: 1. **Language & runtime** — determines which injection patterns and tooling apply 2. **Trust boundaries** — where does untrusted input enter the system? (HTTP params, headers, file uploads, message queues, webhooks) 3. **Authentication model** — JWT, session cookies, API keys, OAuth? 4. **Data sensitivity** — PII, financial data, credentials, health data? 5. **Deployment context** — public internet? internal only? multi-tenant? Context determines severity weighting. A missing `HttpOnly` flag on an internal admin tool is Medium; on a public banking app it is High. ### 1.2 Scan Strategy: Two Layers …

How to install
mdr add northraystudio/maruda/vulnerability-scan@sha256:21a8da25c2acbffeThe line at the top of this page pins the label git:20261105.3036ec6, 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.
