The WP Photo Album Plus WordPress plugin before 9.2.07.002 does not perform any capability or nonce check on one of its public endpoint actions and builds an option name from a client-supplied value without restricting it to its own options, allowing unauthenticated users to read the value of other autoloaded options whose names end in a matching suffix.
