SA-CONTRIB-2026-163: XSS

Published Sep 23, 2026
·
Updated

The Webform module allows site builders to create forms, collect submissions, and configure access to forms and submission data. Site builders may add tooltips and help text to these forms. Some Webform tooltips and help text were not sufficiently sanitized, resulting in possible cross-site scripting (XSS). This vulnerability is mitigated by the fact that an attacker must have permission to create or edit affected Webform configuration or content.
