GHSA-c2xx-cjmh-9q8f Wagtail: Improper restriction handling on descendant collections in Documents and Images API

• PyPI wagtail: < 7.0.9 → fixed in 7.0.9 • PyPI wagtail: >= 7.1, < 7.3.4 → fixed in 7.3.4 • PyPI wagtail: >= 7.4, < 7.4.3 → fixed in 7.4.3 • PyPI wagtail: >= 8.0rc1, < 8.0rc2 → fixed in 8.0rc2

Impact The Documents and Images API V2 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 to the Documents and Images APIs.
