CVE-2026-3056

The Seraphinite Accelerator plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the `seraph_accel_api` AJAX action with `fn=LogClear` in all versions up to, and including, 2.28.14. This makes it possible for authenticated attackers, with Subscriber-level access and above, to clear the plugin's debug/operational logs.
