WEB2 BUG CLASSES — 26 Classes

Root cause, pattern, bypass table, chaining opportunity, real paid examples.

Auth-required classes (🔐): the ones below need at least one logged-in session loaded into the hunt to be testable. Use hunt.py --auth-file .private/T.json or --cookie/--bearer flags — every recon/scan tool then inherits the headers automatically. For IDOR/BOLA/priv-esc, load two sessions (low- and high-priv) and diff. See docs/auth-sessions.md.

🔐 IDOR · Broken Auth/Access Control · Mass Assignment · OAuth/OIDC · JWT · GraphQL field-level auth · LLM/AI chatbot IDOR · MFA (rate-limit + response manipulation tests) · ATO chains · SSRF behind login

The MFA workflow-skip and SAML signature-stripping probes intentionally stay unauthenticated even when a session is loaded — that's the attack premise.
