View online: https://www.drupal.org/sa-contrib-2023-019 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] Reported By:  * Mitch Portier [5] Fixed By:  * micropat [6] * Vladimir Roudakov [7] * Mitch Portier [8] Coordinated By:  * Damien McKenna [9] of the Drupal Security Team [1] https://www.drupal.org/project/addtoany [2] https://www.drupal.org/security-team/risk-levels [3] https://www.drupal.org/project/addtoany/releases/2.0.4 [4] https://www.drupal.org/project/addtoany/releases/8.x-1.21 [5] https://www.drupal.org/user/2284182 [6] https://www.drupal.org/user/260224 [7] https://www.drupal.org/user/673120 [8] https://www.drupal.org/user/2284182 [9] https://www.drupal.org/user/108450
