Wagtail is an open source content management system built on Django. In versions prior to 7.0.8, 7.3.3 and 7.4.2, due to a missing permission check on the image preview endpoint, a user with access to the Wagtail admin can preview any image.

This issue has been fixed in versions 7.0.8, 7.3.3, and 7.4.2.
