Summary
In Wagtail, an open source CMS built on Django, versions prior to 7.0.8, 7.3.3, and 7.4.2, the Documents and Images chooser's chosen endpoint incorrectly listed items for which the user has not been granted choose permission. A user with access to the Wagtail admin could see the filename, name, and URLs of documents and images in those collections.
Risk Assessment
The risk is unauthorized disclosure of metadata (filenames, names, and URLs) of documents and images in collections the user does not have choose permission for. The vulnerability is only exploitable by users with Wagtail admin access, not by ordinary site visitors.
Recommendation
Immediately upgrade Wagtail to version 7.0.8, 7.3.3, or 7.4.2, depending on your release branch. After the update, the vulnerability will be fixed.
