Description

CVE-2026-87828 is a vulnerability in the Seraphinite Accelerator WordPress plugin before version 2.29.24. It allows authenticated users with low privileges, such as subscribers, to trigger a denial of service by submitting a malformed value via an AJAX action that lacks proper capability checks. This causes an uncaught error on every subsequent admin page load, rendering the entire admin area inaccessible to administrators.
