Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

Auth Bypass: Signature generation did not bind the HTTP method, allowing an attacker to replay a signed request with a different method (e.g., POST vs GET) and still pass authentication.

Auth Bypass: Authentication lacked timestamp validation, enabling replay attacks within a valid window, and failures were not raised explicitly, masking invalid attempts.

Authentication Bypass: The authenticate_by_token! method did not require an auth_version parameter, so omitting it could bypass authentication entirely.
