Project: CKEditor 5 Premium Features [1]
Date: 2025-December-03
Security risk: *Moderately critical* 13 ∕ 25
AC:Basic/A:None/CI:Some/II:None/E:Theoretical/TD:All [2]
Vulnerability: Access bypass

Affected versions: <1.2.10 || >=1.3.0 <1.3.6 || >=1.4.0 <1.4.3 || >=1.5.0
<1.5.1 || >=1.6.0 <1.6.4
CVE IDs: CVE-2025-13980
Description: 
The module provides instant integration of the official CKEditor 5 Premium
plugins into the Drupal editor configuration.

This module has a path traversal vulnerability, which allows an access bypass
to restricted image files in the system.

This access bypass is possible for any account with a /View published
content/ permission, but the risk is mitigated by the fact that only images
can be opened.

Solution: 
Install the latest version:

  * If you use the 10.3 or higher or 11.x versions of Drupal core, upgrade the
    module to CKEditor 5 Premium Features 1.6.4 [3].
  * If you use the 10.0 to 10.2 versions of Drupal core, upgrade the module to
    CKEditor 5 Premium Features 1.5.1 [4].
  * If you use the 9.x version of Drupal core, upgrade the module to CKEditor
    5 Premium Features 1.3.6 [5].

A fix was also released to already unsupported branches. However, we
recommend to use the latest version that works with the version of Drupal
core that you're using:

  * CKEditor 5 Premium Features 1.4.3 [6].
  * CKEditor 5 Premium Features 1.2.10 [7].

After the module is updated, if you are using the Export to Word or Export to
PDF plugins, please grant the /Use exporters endpoints/ permission to roles
that are allowed to use text formats with export plugins enabled.
