Hunt WebSocket vulnerabilities — Cross-Site WebSocket Hijacking (CSWSH), missing/weak Origin validation on the WS handshake, no per-message authentication, message tampering, socket.io namespace/room authorization bypass, and handshake-layer Upgrade smuggling. Use when target has WebSocket endpoints (ws:// or wss://), socket.io / SignalR / Phoenix Channels, real-time features, chat, live dashboards, notifications, or trading platforms.
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
# HUNT-WEBSOCKET — WebSocket Security ## Crown Jewel Targets CSWSH (Cross-Site WebSocket Hijacking) with a cookie-authenticated handshake and no CSRF/per-connection token = High–Critical (real-time exfil of any logged-in victim's data). **Highest-value chains:** - **CSWSH → data exfil / ATO** — handshake authenticates via ambient cookie, no CSRF token, Origin not enforced → attacker page opens WS as the victim and streams their messages/PII/tokens. If the stream carries a session/refresh/CSRF token, this escalates to ATO. - **No per-message auth** — HTTP/handshake auth present but individual WS frames are not re-authorized → privileged messages accepted (`deleteUser`, `getSecretConfig`). - **Message tampering** — modify in-flight frames (price, qty, userId, amount) in trading/game/checkout apps → financial fraud. - **socket.io namespace / room authz bypass** — connect to a privileged namespace or join another user's room without a permission check → cross-tenant real-time exfil. …

How to install
mdr add novaestellar/novahaku/hunt-websocket@sha256:b4001c93e6300820The line at the top of this page pins the label git:20260910.546fe86, 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.
