Vulnerability: 
Access bypass, Information Disclosure
Affected versions: 
<1.8.0 || >=2.0.0 <2.0.0-beta3
CVE IDs: 
CVE-2024-13278
Description: 

This module adds a tab for sufficiently permissioned users. The tab shows all revisions like standard Drupal but it also allows pretty viewing of all added/changed/deleted words between revisions.

The module doesn't sufficiently check revision access before rendering a diff report for 1) nodes or 2) general entities that support diff.

This vulnerability is mitigated by the fact that an attacker must have a role with the permission from the general node permission to "view all revisions", one of the more specific node type permissions, "view %bundle revisions" or the equivalent for other general entity types.

Solution: 

Install the latest version:

  • If you use the Diff module for Drupal, upgrade to Diff 8.x-1.8
