Falang multilanguage for WordPress <= 1.3.52 - Missing Authorization to Translation Update and Information Exposure

The Falang multilanguage for WordPress plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on several functions in all versions up to, and including, 1.3.52. This makes it possible for authenticated attackers, with Subscriber-level access and above, to update and delete translations and expose the administrator email address.
