Project: Form mode manager [1]
Date: 2021-July-21
Security risk: *Moderately critical* 11∕25
AC:Basic/A:User/CI:None/II:Some/E:Proof/TD:Default [2]
Vulnerability: Access bypass

Description:
This module provides a user interface that allows the implementation and use
of /Form modes/ without custom development.

The module does not sufficiently respect access restrictions to entity forms
for routes it creates to use specific form modes.

This vulnerability is mitigated by the fact that an attacker must have a
role
with the permission to use a specific form mode, for example use X form
mode.

Solution:
Install the latest version:

   * If you use the Form mode manager module 8.x-1.x series for Drupal 8,
     upgrade to form_mode_manager 8.x-1.4 [3].

   * Jason Partyka [5]
   * Bec  [6]

Fixed By:
   * Byron Duvall [7]
   * Derek Wright [8]

Coordinated By:
   * Greg Knaddison [9] of the Drupal Security Team
   * Damien McKenna [10] of the Drupal Security Team
