Real-World Exposure

Description
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

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for wagtail, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update wagtail to 7.0.9 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-55468 is resolved across your whole dependency graph.
Workarounds
Put an independent control in front of the weakness: restrict the affected endpoint or interface to trusted networks, require an additional authentication factor or proxy-level check, and invalidate existing sessions and credentials in case the flaw has already been used.
