## Overview

### Impact

The Documents and Images [API V2](https://docs.wagtail.org/en/stable/advanced_topics/api/index.html) incorrectly listed items in descendants of private collections, which should inherit the view restrictions defined on their ancestors. A user with access to the API could see the filename and name of documents and images in these descendant collections.

### Patches

Patched versions have been released as Wagtail 7.0.9, 7.3.4, 7.4.3 and 8.0rc2.

### Workarounds

Site owners using Wagtail's API can avoid the vulnerability by adding [authentication](https://docs.wagtail.org/en/stable/advanced_topics/api/v2/configuration.html#authentication) to the Documents and Images APIs.
