Quarkus REST Data Panache Endpoint Security Bypass Vulnerability

A flaw was found in Quarkus REST Data Panache. This security bypass vulnerability allows unauthenticated attackers to bypass security controls on generated endpoints.

When a developer customizes a specific operation using @MethodProperties without explicitly re-declaring security roles, the code generator silently drops class-level security requirements.

This results in the affected endpoint defaulting to permissive, unauthenticated access, potentially leading to unauthorized information disclosure or data modification.
