Overview
Affected versions of this package are vulnerable to Improper Authentication due to the unconditional substitution of a nil AuthenticationFunc with a no-op function in the Load process. An attacker can gain unauthorized access to protected endpoints by sending unauthenticated requests, as all security requirements are silently bypassed when the authentication function is not explicitly set.
