CVE-2026-88783

Kubio AI Page Builder < 2.9.3 - Unauthenticated Stored XSS via Comment Content

Published Oct 3, 2026 CVSS 3.1 · 8.8 High EPSS < 1% KEV · Not listed
Description
The Kubio AI Page Builder WordPress plugin before 2.9.3 does not limit its widening of the allowed HTML elements to the editor context, so the wider set is applied when filtering content submitted by unauthenticated users as well, allowing them to store markup which the Kubio AI Page Builder WordPress plugin before 2.9.3's own script later executes in the browser of any visitor, or of an administrator reviewing the still-unapproved submission.
