JWT Token Security:
Protected against algorithm switching attacks by validating and whitelisting algorithms (RS256, RS384, RS512, PS256, PS384, PS512, ES256, ES384, ES512)
Added 2-minute clock skew tolerance for time-based validations
Added "not before" (nbf) claim validation with clock skew tolerance
Required JWT ID (jti) claim to prevent replay attacks
Added strict algorithm validation to prevent downgrade attacks
Session Management Security:
Implemented cryptographically secure random cookie names to prevent targeting

Implemented session pooling for secure resource management
Added secure session cleanup on expiration
Configuration and URL Security:
Enforced HTTPS for all provider URLs and external endpoints
Added minimum rate limit (10 req/sec) to prevent DOS attacks
Added strict validation for excluded URLs:
Must start with "/"
No path traversal (..)
No wildcards (*)
Made ForceHTTPS true by default for secure cookies
Added validation for secure redirect URIs
Added validation for all OIDC endpoints (must be HTTPS)
Added secure defaults in configuration
Test Coverage:
Added comprehensive test cases verifying all security validations
