The RevivePress – Keep your Old Content Evergreen plugin for WordPress is vulnerable to unauthorized access and modification of data due to a missing capability check on the import_data and copy_data functions in all versions up to, and including, 1.5.6. This makes it possible for authenticated attackers, with subscriber-level access or higher, to overwrite plugin settings and view them.
