This module integrates the Tagify JavaScript library to enhance entity reference selection in entity reference widgets.
The module does not properly sanitise the name of parent taxonomy terms when rendering suggestions in the Tagify dropdown. This results in a cross-site scripting vulnerability that may allow attackers to execute arbitrary JavaScript in the context of the user’s session.
The vulnerability is mitigated by the fact an attacker must have a role with permission to create or edit taxonomy terms in a vocabulary.
