lukaszraczylo a750c4f5b9 Size computation for allocation may overflow (#99)
* Size computation for allocation may overflow

Performing calculations involving the size of potentially large strings or slices can result in an overflow (for signed integer types) or a wraparound (for unsigned types). An overflow causes the result of the calculation to become negative, while a wraparound results in a small (positive) number.

* Issue #53: Fix CSRF token handling in reverse proxy

1.  HTTPS Detection Fixed (session.go:723)
- Now uses X-Forwarded-Proto header instead of r.URL.Scheme
- Properly detects HTTPS in reverse proxy environments
2.  SameSite Cookie Attribute Fixed
- Removed automatic SameSiteStrictMode for HTTPS (would break OAuth)
- Keeps SameSiteLaxMode to allow OAuth callbacks from external domains
- Only uses Strict for AJAX requests which don't involve OAuth redirects
3.  Cookie Domain Handling Fixed
- Now respects X-Forwarded-Host header for cookie domain
- Ensures cookies are set for the public domain, not internal proxy domain
4.  EnhanceSessionSecurity Properly Integrated
- Function is now actually called during session save
- Applies security enhancements without breaking OAuth flow

Why Issue #53 Failed Before:

1. Cookies were not marked Secure in HTTPS environments (browser wouldn't send them back)
2. If they had been Secure with SameSite=Strict, Azure callbacks would still fail
3. Cookie domain might have been wrong (internal vs public domain)

Why It Works Now:

1. Cookies are properly marked Secure for HTTPS
2. Uses SameSite=Lax to allow OAuth provider callbacks
3. Cookie domain uses public domain from X-Forwarded-Host
4. CSRF token persists through the entire OAuth flow

* Next set of enhancements together with memory usage improvements.

* Memory leak fixes and optimisations.

lukaszraczylo 17dea67229 Security improvements have been implemented and verified across four main areas:
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
