This medium-severity CVE scores 4.3 under the CNA's CVSS (NVD's own analysis pending). EPSS exploit-prediction score not yet available (the EPSS model rescores nightly; freshly-published CVEs typically appear within 48 hours). GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

Wagtail: Improper restriction handling on Pages admin API

Impact

The internal Pages admin API incorrectly returns page fields without access control when they are declared in api_fields. A user with access to the Wagtail admin can use this API to fetch draft and live page fields’ contents that are part of api_fields on the base page model (title, slug, seo_title, search_description), as well as all custom fields declared in api_fields.

The vulnerability is not exploitable by an ordinary site visitor without access to the Wagtail admin.

Patches

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

Workarounds

Site owners unable to upgrade can apply the fix by overriding the relevant method on PagesAdminAPIViewSet to patch all vulnerable admin API endpoints:

# wagtail_hooks.py or AppConfig.ready()
from wagtail.admin.api.views import PagesAdminAPIViewSet
from wagtail.permissions import page_permission_policy
def _restricted_get_base_queryset(self):
    return page_permission_policy.explorable_instances(self.request.user)
PagesAdminAPIViewSet.get_base_queryset = _restricted_get_base_queryset
