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]
