Description
The Kraken.io Image Optimizer plugin for WordPress is vulnerable to authorization bypass due to a missing capability check on its AJAX actions in versions up to, and including, 2.6.8. This makes it possible for authenticated attackers, with subscriber-level permissions and above, to reset image optimizations.
