Advisory
Source description from Wordfence Intelligence, credited to Tomi Ashari.
The Loco Translate WordPress plugin before 2.5.4 mishandles data inputs which get saved to a file, which can be renamed to an extension ending in .php, resulting in authenticated "translator" users being able to inject PHP code into files ending with .php in web accessible locations.
