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]
