Description
The Schema App Structured Data plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the MarkupUpdate function in all versions up to, and including, 2.2.0. This makes it possible for authenticated attackers, with subscriber access or higher, to update or delete post metadata.
