Seraphinite Accelerator <= 2.29.23 - Authenticated (Subscriber+) Full Admin Area Denial of Service
The Seraphinite Accelerator plugin for WordPress is vulnerable to Denial of Service in all versions up to, and including, 2.29.23. This is due to a missing capability check on the OnAdminApi_StateSet AJAX handler, allowing low-privileged users to write malformed state values. This makes it possible for authenticated attackers, with subscriber-level access and above, to cause an uncaught error on every admin page load, rendering the entire WordPress admin area inaccessible to all administrators.
