View online: https://www.drupal.org/sa-contrib-2026-180 Project: Mermaid Diagram Field [1] Project machine name: mermaid_diagram_field Date: 2026-September-23 Security risk: *Moderately critical* 13 ∕ 25 AC:None/A:User/CI:Some/II:None/E:Theoretical/TD:All [2] Vulnerability: Access bypass Affected versions: >=1.0.4 <1.0.9 CVE IDs: CVE-2026-96384 Description: This module enables you to add mermaid diagram that displays either inline on an entity or optionally in a modal. The module doesn't sufficiently respect default revision behavior and does not properly limit access to the modal content. This vulnerability is mitigated by the fact that an attacker must have the modal display option enabled for the field, or otherwise know the route of the modal and entity ID. Solution: Install the latest version: * If you use the Mermaid Diagram Field module, upgrade to Mermaid Diagram Field 1.0.10 [3].
