Project: Linkit [1]
Date: 2021-September-29
Security risk: *Moderately critical* 12∕25
AC:Basic/A:Admin/CI:Some/II:Some/E:Theoretical/TD:Default [2]
Vulnerability: Cross Site Scripting

Description: 
Linkit provides an easy interface for internal and external linking with
WYSIWYG editors by using an autocomplete field.

It does not sufficiently sanitize user input.

This vulnerability is mitigated by the fact that an attacker must have a role
with the permission to create or edit an entity bundle.

Solution: 
Install the latest version:

   * If you use the Linkit module for Drupal 8.x, upgrade to Linkit 8.x-4.4
