Project: AT Internet SmartTag [1] Date: 2026-January-14 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: <1.0.1 CVE IDs: CVE-2026-0946 Description:  This module integrates the AT Internet SmartTag service.

The module does not filter administrator-entered text leading to a persistent Cross-site Scripting (XSS) vulnerability.

This vulnerability is mitigated by the fact that an attacker must have a role with the permission "administer atsmarttag".

Solution:  Install the latest version and confirm the permissions associated with the module are assigned to appropriate roles.

* If you use the AT Internet SmartTag module for Drupal 9 and 10, upgrade to AT Internet SmartTag 1.0.1 [3]
