Project: Client-side Hierarchical Select [1]
Date: 2021-September-22
Security risk: *Moderately critical* 13∕25
AC:Basic/A:User/CI:Some/II:Some/E:Theoretical/TD:Default [2]
Vulnerability: Cross-site scripting

Description: 
The module provides a field widget for selecting taxonomy terms in a
hierarchical fashion.

The module doesn't sanitize user input in certain cases, leading to a
possible Cross-Site-Scripting (XSS) vulnerability.

This vulnerability is mitigated by the fact that an attacker must have a role
with permission to create or edit taxonomy terms to which the widget may
apply.

Solution: 
Install the latest version:

   * If you use the cshs module for Drupal 8 or 9, upgrade to Client-side
     Hierarchical Select 8.x-3.5 [3].
