CVE-2026-55468 · Severity: medium · CVSS 4.3 · Published 2026-08-24

Wagtail is a Django-based content management system used to build and manage websites. The internal Pages admin API fails to properly restrict access to page content fields, allowing any user with Wagtail admin credentials to retrieve draft and published page data (titles, descriptions, custom fields) regardless of their intended permissions. This could expose sensitive or unpublished content to unauthorized internal users.

## Technical details

The vulnerability exists in the PagesAdminAPIViewSet class where the get_base_queryset() method fails to apply page permission policies when filtering queryable pages. An authenticated user with access to the Wagtail admin interface can craft requests to the internal Pages admin API to retrieve all page fields declared in api_fields (including title, slug, seo_title, search_description, and custom fields) without proper authorization checks. The vulnerability requires prior authentication to the Wagtail admin and is not exploitable by unauthenticated site visitors. Patches are available in Wagtail 7.0.9, 7.3.4, 7.4.3, and 8.0rc2, and a workaround is provided by applying a custom permission policy to the viewset.
