The service authentication token in P4 Search container images is reset to a publicly documented default value, enabling unauthenticated network attackers to obtain the highest application privilege level. This authentication bypass allows direct access to the P4 Search service without valid credentials, and when connected to a P4 Server, can be leveraged to achieve arbitrary code execution on the server infrastructure.
