The WP Photo Album Plus WordPress plugin before 9.2.07.002 does not validate a client-controlled value used to build a file path in one of its public endpoint actions, and performs no authorisation check on it, allowing unauthenticated attackers to delete arbitrary ZIP archives on the server, including ones stored outside the web root.
