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
Added automatic session ID rotation after successful login to prevent session fixation
Enforced 24-hour absolute session timeout
Added strict encryption key length validation (minimum 32 bytes)
Added comprehensive session validation including timeout checks
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
Added test cases for HTTPS enforcement on all endpoints
Added test cases for minimum rate limits
Added test cases for secure session management
Added test cases for token validation with clock skew
Added test cases for secure configuration defaults
All security improvements have been verified through passing test cases, protecting against:
Session fixation attacks
Token replay attacks
Algorithm switching attacks
Path traversal attacks
Session hijacking
Timing attacks
DOS attacks
Man-in-the-middle attacks through enforced HTTPS
Reduced connection timeouts from 30s to 15s
Decreased idle connection limits from 100 to 30
Lowered keepalive duration from 90s to 30s
Added MaxConnsPerHost limit of 50 to prevent connection flooding
Optimized TLS handshake timeout to 5s
Cache System Optimization:
Implemented size-limited LRU cache with max 1000 items
Added efficient eviction of least recently used items
Improved cleanup process with batch operations
Reduced lock contention by splitting read/write operations
Optimized memory usage with access tracking
Added immediate cleanup of expired items during access
Connection Management:
Enabled connection reuse with keepalives
Reduced connection pool size to conserve memory
Implemented more aggressive connection timeout
Added connection limits per host to prevent resource exhaustion
Removed global metadata cache and sync.Once
Each middleware instance now handles its own metadata initialization
Added tests to verify multiple instances work correctly
The changes ensure that:
Each route gets its own properly initialized middleware instance
Metadata is fetched and set correctly for each instance
No shared state between instances that could cause conflicts
Each instance can handle requests independently
The added test verifies this by creating multiple middleware instances with different routes and confirming they all initialize and function correctly. The test specifically checks that:
Each instance initializes successfully
Each instance gets its own metadata configuration
Each instance can handle requests independently
Callback URLs are correctly set per route
