What is DRUPAL-CONTRIB-2023-019?
DRUPAL-CONTRIB-2023-019 is a cross-site scripting vulnerability in drupal/addtoany, published on 31 May 2023. Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.
Official 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".
