Authentication and Authorization Router

This is the routing entry point for authentication, sessions, and authorization boundaries.

Use it to decide whether the issue is mainly login mechanics, object-level authorization, browser trust boundaries, or identity protocols such as OAuth/JWT/SAML before going deeper.

When to Use

• The target includes login, registration, password reset, 2FA, sessions, JWT, OAuth, or SSO
• You suspect object authorization flaws, cross-tenant access, cross-origin reads, CSRF, or protocol misconfiguration
• You need to decide whether to test authentication or authorization first

Skill Map

• Authentication Bypass: login bypass, password reset, 2FA, enumeration, brute-force protections
• IDOR Broken Object Authorization: IDOR, BOLA, BFLA, missing object permissions
• JWT OAuth Token Attacks: algorithm confusion, key trust issues, claim abuse, token forgery
• OAuth OIDC Misconfiguration: redirect URI, state, nonce, PKCE, account binding
• CSRF Cross Site Request Forgery: CSRF tokens, SameSite, JSON CSRF, login CSRF
• CORS Cross Origin Misconfiguration: reflected Origin, credentialed cross-origin reads, allowlist bypass
• SAML SSO Assertion Attacks: assertion wrapping, signature validation, audience, ACS boundaries

Recommended Flow

1. First confirm the authentication model and session boundaries
2. Then confirm object-level and function-level authorization
3. Then move to token, cross-origin, and protocol details
4. If enterprise federation exists, continue with OAuth, OIDC, or SAML topics
