CVE-2026-87828 Details
Description
The Seraphinite Accelerator WordPress plugin before 2.29.24 does not perform a capability check on one of its state-update AJAX actions, allowing authenticated users such as subscribers to write a malformed value that causes an uncaught error on every subsequent admin page load, making the entire admin area inaccessible to all administrators (denial of service).
A denial-of-service vulnerability has been identified in the Seraphinite Accelerator WordPress plugin, affecting versions prior to 2.29.24. The issue arises because the plugin does not perform a capability check on one of its state-update AJAX actions. This oversight allows authenticated users, such as subscribers, to send a malformed value that triggers an uncaught error. As a result, every subsequent admin page load encounters this error, rendering the entire admin area inaccessible to all administrators.
Users are advised to update the Seraphinite Accelerator WordPress plugin to version 2.29.24 or later.
