Hunting skill for xss vulnerabilities. Built from 174 public bug bounty reports. Use when hunting xss on any target.
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
## Crown Jewel Targets XSS is high-value when it combines **privileged context + persistent delivery + scope escalation**. The highest payouts come from: - **Admin panels and authenticated dashboards** (e.g., `*/admin`, `*/settings`) — attacker can hijack sessions with elevated privileges, exfiltrate tokens, or pivot to account takeover - **Payment/financial flows** (`paypal.com`, checkout pages, currency converters) — XSS here enables credential harvesting and financial fraud at scale - **Stored XSS in collaborative features** (wikis, markdown renderers, issue trackers, RDoc, labels, tags) — one payload infects every viewer, multiplying impact - **SSO/signin pages** (e.g., `paypal.com/signin`) — XSS here is critical because it can steal auth tokens across the entire platform - **Shared SaaS tenant surfaces** (`*.myshopify.com`, `api.collabs.*`) — XSS in one tenant's context can bleed across tenant boundaries - **Help/documentation sites** (`help.shopify.com`) — lower severity individually, but often have looser sanitization and trusted user perception - **SVG/file upload endpoints** — frequently bypasses CSP and sanitization simultaneously …

How to install
mdr add adriannoes/awesome-agentic-ai/hunt-xss@sha256:2b8a98d7560bf32eThe line at the top of this page pins the label git:20260611.ff4cc7c, 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.
