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.
