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]
