Project: Scheduler [1]
Project machine name: scheduler
Date: 2026-November-04
Security risk: *Moderately critical* 13 ∕ 25
AC:Basic/A:User/CI:Some/II:Some/E:Theoretical/TD:Default [2]
Vulnerability: Access bypass

Affected versions: <1.7.0 || >=2.2.0 <2.2.3 || 2.0.* || 2.1.*
CVE IDs: CVE-2026-122075
Description: 
This module enables you to schedule content to be published or unpublished at
a certain time in the future.

The module doesn't sufficiently check if a user has permission to change
publication or unpublication dates. This might cause certain information to
be publicly disclosed ahead of the scheduled time, or content to become
inaccessible earlier or later than planned.

This vulnerability is mitigated by the fact that an attacker must already
have permission to edit the affected content, and the content must be
editable through a web services API like JSON:API or REST.

Solution: 
Install the latest version:

 * If you use version 8.x-1.x, upgrade to Scheduler 8.x-1.7 [3].
 * If you use version 2.2.x, upgrade to Scheduler 2.2.3 [4].
 * If you use version 2.3.x, upgrade to Scheduler 2.3.1 [5].
 * Version 2.1.x branch is no longer supported. Sites on this version should
   update to 2.2.3 or 2.3.1.
