Webform does not sufficiently sanitise text counter settings before passing them to its bundled jQuery Text Counter library, which can lead to cross-site scripting under certain configurations. An attacker must be able to create or edit affected Webform elements, or place specially crafted counter markup on a page where the Webform counter JavaScript is active.

Look for drupal/webform and its version in composer.lock. The advisory lists fixes in 6.2.12 and 6.3.1 but gives no affected version ranges. Review text counter configuration on Webform elements, who can create or edit those elements, and whether users can place counter markup on pages where the Webform counter JavaScript is active.

The vulnerability is mitigated by the requirement that an attacker can create or edit affected Webform elements, or place specially crafted counter markup on a page where the Webform counter JavaScript is active.

The Webform module allows site builders to create forms, collect submissions, and configure access to forms and submission data.

The module does not sufficiently sanitize text counter configuration before passing options to the bundled jQuery Text Counter library. Under certain configurations, this can allow markup from counter-related settings to be inserted into the page leading to a cross-site scripting vulnerability.

This vulnerability is mitigated by the fact that an attacker must be able to create or edit affected Webform elements, or place specially crafted counter markup on a page where the Webform counter JavaScript is active.
