Project: AddToAny Share Buttons [1] Date: 2023-May-31 Security risk: *Moderately critical* 13∕25 AC:Basic/A:Admin/CI:Some/II:Some/E:Theoretical/TD:All [2] Vulnerability: Cross Site Scripting
Description: This module provides social media share & follow buttons.
The module doesn't sufficiently restrict AddToAny block settings to users who have permission to administer AddToAny. This allows users with lower permission to configure malicious code 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 blocks".
Solution: Install the latest version:
* If you use the AddToAny Share Buttons module for Drupal 9.4+ or 10, upgrade to AddToAny 2.0.4 [3] * If you use the AddToAny Share Buttons module for Drupal versions before 9.4, upgrade to AddToAny 8.x-1.21 [4]
