Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Wagtail versions before 7.0.8, from 7.1 before 7.3.3, and from 7.4 before 7.4.2 are affected. A user with access to the Wagtail admin can see the filenames, names and URLs of documents and images in collections they lack choose permission for, because the Documents and Images chooser's chosen endpoint lists items without checking that permission. Upgrade to Wagtail 7.0.8, 7.3.3, or 7.4.2. The source lists no workarounds.
