Advisory

Source description from Wordfence Intelligence, credited to Dhabaleshwar Das.

The Appsero analytics tool used in several plugins is vulnerable to unauthorized modification of data due to a missing capability check on the handle_optin_optout function in versions up to, and including, 2.0.0. This makes it possible for unauthenticated attackers to opt-in or opt-out of tracking. This was patched in version 2.0.1 of Appsero with a nonce check.
