Hunt for exploitable, bounty-worthy security issues in repositories. Focuses on remotely reachable vulnerabilities that qualify for real reports instead of noisy local-only findings.
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
# Security Bounty Hunter Use this when the goal is practical vulnerability discovery for responsible disclosure or bounty submission, not a broad best-practices review. ## When to Use - Scanning a repository for exploitable vulnerabilities - Preparing a Huntr, HackerOne, or similar bounty submission - Triage where the question is "does this actually pay?" rather than "is this theoretically unsafe?" ## How It Works Bias toward remotely reachable, user-controlled attack paths and throw away patterns that platforms routinely reject as informative or out of scope. ## In-Scope Patterns These are the kinds of issues that consistently matter: | Pattern | CWE | Typical impact | | --- | --- | --- | | SSRF through user-controlled URLs | CWE-918 | internal network access, cloud metadata theft | | Auth bypass in middleware or API guards | CWE-287 | unauthorized account or data access | | Remote deserialization or upload-to-RCE paths | CWE-502 | code execution | | SQL injection in reachable endpoints | CWE-89 | data exfiltration, auth bypass, data destruction | | Command injection in request handlers | CWE-78 | code execution | …

How to install
mdr add jdanigo/hydraia/security-bounty-hunter@sha256:7b3163f0ba54946eThe line at the top of this page pins the label v1.0.0, 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.
