CVE-2026-55793

Name of the Vulnerable Software and Affected Versions Craft CMS versions 5.0.0-RC1 through 5.9.22

Description A stored cross-site scripting issue exists where a user with author-level control panel permissions can embed a malicious JavaScript payload within an entry title. The execution occurs when an administrator or a user with saveEntries permissions for the same Structure section performs a drag operation on another entry under the affected entry in the table view. This happens because the server escapes the title into data-title, which the browser decodes and jQuery reads via .data('title'), subsequently concatenating it into a new HTML string without proper attribute escaping. Successful exploitation requires the attacker to have at least an Author role and the victim to perform a specific drag action while possessing elevated session privileges.

Recommendations Update to version 5.9.23.
