Project: Webform [1]
Project machine name: webform
Date: 2026-September-23
Security risk: *Moderately critical* 10 ∕ 25
AC:Complex/A:Admin/CI:Some/II:Some/E:Theoretical/TD:Uncommon [2]
Vulnerability: Cross-site scripting

Affected versions: <6.2.12 || >=6.3.0 <6.3.1
CVE IDs: CVE-2026-96363
Description: 
The Webform module allows site builders to create forms, collect submissions,
and configure access to forms and submission data.

Webform includes a submodule called Webform Entity Print. This submodule
doesn't sufficiently limit access to its print templates. When the submodule
is enabled, a user with permissions to create a webform can exploit
cross-site scripting (XSS) in submodule settings.

This vulnerability is mitigated by the fact that an attacker must have a role
with /create webform/ and /edit own webform/ permissions, and the Webform
Entity Print module must be enabled.

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].
