Project: Simple multi step form [1] Date: 2025-November-05 Security risk: *Moderately critical* 13 ∕ 25 AC:Basic/A:Admin/CI:Some/II:Some/E:Theoretical/TD:All [2] Vulnerability: Cross-site Scripting

Affected versions: <2.0.0 CVE IDs: CVE-2025-12761 Description:  This module provides the ability to convert any entity form into a simple multi-step form.

The module doesn’t sufficiently filter certain user-provided text leading to a cross-site scripting (XSS) vulnerability.

This vulnerability is mitigated by the fact that an attacker must have a role with the permission “administer node form display”.

Solution:  Install the latest version:

* If you use the Simple multi step form module for Drupal, upgrade to a release from the 2.x branch [3], as the 8.x-1.x branch is now unsupported
