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
