Description

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.
