Project: Blazy [1]
Date: 2026-August-26
Security risk: *Less critical* 9 ∕ 25
AC:Basic/A:User/CI:Some/II:None/E:Theoretical/TD:Uncommon [2]
Vulnerability: Access bypass

Affected versions: <3.0.18
CVE IDs: CVE-2026-81165
Description: 
This module enables users to display a field of a target entity through a
Blazy Filter plugin shortcode.

The module does not consistently check entity view access. If a user has
access to a Blazy-enabled text format, this allows them to render a field
from an entity they are not permitted to view.

The issue is mitigated by the fact that the shortcode does not expose the
entire entity. Only fields that the shortcode can render are vulnerable.

Solution: 
Install the latest version:

 * If you use the Blazy module for Drupal, upgrade to Blazy 3.0.18 [3].
