Project: Block Content Revision UI [1]
Date: 2021-June-16
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 to Block Content 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 Block Content Revision UI, and
another affected module must be enabled.

Solution: 
Install the latest version:

  * If you use the Block Content Revision UI module for Drupal 8.x, upgrade 
to
    Block Content Revision UI 2.127.1 [3]
