Project: Responsive Favicons [1] Date: 2026-February-25 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: <2.0.2 CVE IDs: CVE-2026-3218 Description:  This module adds the favicons generated by realfavicongenerator.net to your Drupal site.

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 responsive favicons".

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

* If you use the Responsive Favicons module version 2.0.1 or lower, upgrade to Responsive Favicons 2.0.2 [3]. * 4.x and 3.x branches are not affected by this vulnerability.
