Project: Webform [1]
Project machine name: webform
Date: 2026-September-23
Security risk: *Moderately critical* 13 ∕ 25
AC:Basic/A:User/CI:Some/II:Some/E:Theoretical/TD:Default [2]
Vulnerability: Cross-site scripting

Affected versions: <6.2.12 || >=6.3.0 <6.3.1
CVE IDs: CVE-2026-96358
Description: 
The Webform module allows site builders to create forms, collect submissions,
and configure access to forms and submission data.

The module includes a rating element, which did not sufficiently validate its
data. Under specific circumstances, this could allow cross-site scripting on
a page with a rating element.

This vulnerability is mitigated by the fact that an attacker must be able to
place crafted HTML markup on the same page as a Webform rating element.

Solution: 
Install the latest version:

 * If you use the 6.2.x branch of Webform upgrade to Webform 6.2.12 [3].
 * If you use the 6.3.x branch of Webform, upgrade to Webform 6.3.1 [4].
