CVE-2026-54261 (opens in a new tab)How to fix?
Upgrade wagtail to version 7.0.8, 7.3.3, 7.4.2 or higher.
Overview
wagtail is an open source content management system built on Django.
Affected versions of this package are vulnerable to Improper Handling of Insufficient Permissions or Privileges via the preview view in wagtail/images/views/images.py. An attacker can preview images they do not have access to by sending a preview request for an arbitrary image ID from the Wagtail admin. A user with admin access but without change permission on a specific image can reach the preview endpoint and render that image anyway, exposing the image content through the preview page.
Notes
- The vulnerable path was only exposed through the Wagtail admin preview flow; ordinary site visitors without admin access were not in scope.
- Impact is limited to preview rendering of the image, not disclosure of the image object’s stored metadata or other fields.
