Project: Linky Revision UI [1]
Date: 2021-June-30
Security risk: *Moderately critical* 11∕25
AC:Complex/A:User/CI:Some/II:Some/E:Theoretical/TD:Uncommon [2]
Vulnerability: Access bypass

Description: 
This module provides a revision UI for Linky entities.

The module doesn't sufficiently respect access restrictions to certain
entities when used in conjunction with specific modules.

This vulnerability is mitigated by the fact that an attacker must have a role
with any of the permissions provided by Linky Revision UI, and another
affected module must be enabled.

Solution: 
Install the latest version:

   * If you use the Linky Revision UI module for Drupal 8.x, upgrade to Linky
     Revision UI 2.127.2 [3]
