Project: Role Delegation [1]
Date: 2026-January-14
Security risk: *Moderately critical* 13 ∕ 25
AC:Basic/A:User/CI:Some/II:Some/E:Theoretical/TD:Default [2]
Vulnerability: Access bypass

Affected versions: >=1.3.0 <1.5.0
CVE IDs: CVE-2026-0945
Description: 
This module allows site administrators to grant specific roles the authority
to assign selected roles to users, without them needing the "administer
permissions" permission.

The module contains an access bypass vulnerability when used in combination
with the Views Bulk Operations module. A user with the ability to delegate a
role is also able to assign the administrator role, including to their own
user.

This vulnerability is mitigated by the fact that an attacker must have access
to a view of users with the Views Bulk Operations module enabled.

Solution: 
Install the latest version:

  * If you use the Role Delegation module for Drupal ^10.3 || ^11, upgrade to
    Role Delegation 8.x-1.5 [3]
