SA-CONTRIB-2026-104: Critical severity drupal/blazy vulnerability
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.
