Hunt Forgot Password / Account Recovery Authentication Flaws — 5 distinct patterns: (1) username enumeration via different responses for valid vs invalid email, (2) reset token exposed directly in the API response body, (3) reset token not invalidated after use (replay), (4) password reset link works from a different IP/browser (no binding), (5) no rate limit on the reset request endpoint. These are the standalone recovery-flow broken-auth primitives — distinct from reset-email host-header…
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
**Trigger**: Hunting password reset, account recovery, or forgot-password authentication flaws — username enumeration via reset, reset token exposure, token replay, rate-limit bypass on reset endpoint.
## Autonomous Testing Priority
**Start with username enumeration — it's the fastest win and gates the rest.**
**Pattern 1 — Username enumeration (response difference for valid vs invalid email):**
1. POST to the forgot-password endpoint with a clearly invalid email (e.g. `nonexistent@fakedomain12345.com`) — record the response body, status code, and length
2. POST with an email you know exists (or try common patterns like `admin@target.com`, `test@target.com`, `user@target.com`)
3. Compare responses: different message ("Email sent" vs "Email not found"), different HTTP status, or meaningfully different body length = username enumeration confirmed
4. Proof: enumeration is confirmed when the two responses differ measurably (baseline vs probe) in message text, status code, or body length
**Pattern 2 — Reset token exposed in the API response:**

How to install
mdr add novaestellar/novahaku/hunt-forgot-password@sha256:7ba5957f0eed0b0dThe 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.
