View online: https://www.drupal.org/sa-contrib-2022-026 Project: Entity Reference Tree Widget [1] Date: 2022-February-23 Security risk: *Moderately critical* 12∕25 AC:Complex/A:Admin/CI:Some/II:Some/E:Theoretical/TD:All [2] Vulnerability: Cross Site Scripting Description:  This module provides an entity relationship hierarchy tree widget for an entity reference field. The module doesn't sufficiently filter on output, leading to a Cross Site Scripting vulnerability. This vulnerability is mitigated by the fact that an attacker must have a role with the permission to modify an entity that is the reference to a field. Solution:  Install the latest version: * If you use the Entity Reference Tree Widget module for Drupal 8.x or 9.x, upgrade to entity_reference_tree 2.0.2 [3] Reported By:  * Jeroen Vreuls [4] Fixed By:  * Mingsong [5] * Jeroen Vreuls [6] Coordinated By:  * Chris McCafferty [7] of the Drupal Security Team * Damien McKenna [8] of the Drupal Security Team [1] https://www.drupal.org/project/entity_reference_tree [2] https://www.drupal.org/security-team/risk-levels [3] https://www.drupal.org/project/entity_reference_tree/releases/2.0.2 [4] https://www.drupal.org/user/2700643 [5] https://www.drupal.org/user/2986445 [6] https://www.drupal.org/user/2700643 [7] https://www.drupal.org/user/1850070 [8] https://www.drupal.org/user/108450
