Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: HTTP request method spoofing allowed arbitrary clients to bypass restricted routing and authorization controls if HTTP method overrides were processed on non-POST requests or without explicit toggle configurations.
Session Fixation: Session cookies could be established without security-critical attributes (HttpOnly and SameSite) because user-defined configuration blocks failed to propagate down to the final cookie emission helper.
Auth Bypass: Reusing the same cookie driver or in-memory cookie storage instance across multiple requests led to cross-request session leakage, allowing unauthorized users to gain hijacked active sessions.
