Summary
Craft CMS: Stored XSS via Structure entry title in table view
Details

Craft CMS is a content management system (CMS). In versions 5.0.0-RC1 through 5.9.22, an author-level control panel user can store a malicious JavaScript payload in an entry title. When an admin, or any control panel user with saveEntries for the same Structure section, drags another entry under the poisoned entry in table view, the payload executes in the victim’s session. The issue is exploitable because the title is escaped into data-title by the server, decoded again by the browser, read with jQuery .data('title'), and then concatenated into a new HTML string without attribute escaping. To exploit, an attacker must have an existing control panel account (Author role minimum), the victim must perform a drag operation (not just visit the page), and the victim’s session needs to be elevated at trigger time. This issue has been fixed in version 5.9.23.
