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.
