Hunt Session Management vulnerabilities — session fixation (no regeneration on login), insufficient invalidation on logout / password-change / email-change, predictable or low-entropy session IDs, JWT-as-session with no exp/revocation, refresh-token rotation/reuse-detection gaps, OAuth/SSO session linkage, device-bound-session (DBSC) downgrade, and cookie attribute issues (Secure/HttpOnly/SameSite/__Host-). Validate with TWO real sessions (attacker A + victim B), body-diff every 200, and OOB…
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
## Autonomous Testing Priority **Missing HttpOnly on cookies is auto-detected — focus your active testing on lifecycle invalidation (higher impact).** **Pattern 1 — Session survives logout (most common high-value finding):** 1. Login and note the session token/cookie value 2. Call the logout endpoint (`/logout`, `POST /api/logout`, etc.) 3. Try to use the OLD session token to access a protected resource (`/api/me`, `/dashboard`, `/account`) 4. If 200 with user data → session not invalidated on logout = ATO persistence **Pattern 2 — Session not regenerated on login (session fixation):** 1. GET any page to receive a pre-authentication session token/cookie 2. POST valid credentials to the login endpoint 3. Compare the session token BEFORE and AFTER login 4. If the token is unchanged → session fixation vulnerability **Pattern 3 — Session survives password change:** 1. Login → record session A value 2. Change the password via the account settings endpoint 3. Replay session A on a protected endpoint 4. If 200 → token not rotated on credential change = persistent ATO (critical chain when combined with XSS/cookie theft) …

How to install
mdr add novaestellar/novahaku/hunt-session@sha256:f7ea25845514c216The 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.
