Wagtail has improper restriction handling on Documents and Images API

Impact

The Documents and Images API incorrectly listed items in private collections. A user with access to the API could see the filename and name of documents and images in private collections.

Patches

Patched versions have been released as Wagtail 7.0.7 and 7.3.2. The new 7.4 LTS feature release also incorporates this fix.

Workarounds

Site owners using Wagtail's API can avoid the vulnerability by adding authentication to the Documents and Images APIs.
