Machine-written summary

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

Wagtail versions before 7.0.9, 7.1 through before 7.3.4, 7.4 through before 7.4.3, and 8.0rc1 before 8.0rc2 are affected. The internal Pages admin API returns fields declared in api_fields without access control, so a user with Wagtail admin access can read draft and live page field contents, including custom fields. Upgrade to Wagtail 7.0.9, 7.3.4, 7.4.3, or 8.0rc2. Site owners who cannot upgrade can override the relevant method on PagesAdminAPIViewSet to patch the affected endpoints.
