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_querysetAcknowledgements

AnalysisAI
Unauthorized page content disclosure in Wagtail's internal Pages admin API allows any authenticated Wagtail admin user to read draft and live page fields - including title, slug, seo_title, search_description, and all custom fields declared in api_fields - for pages outside their permitted access scope. The root cause is CWE-280: the get_base_queryset method on PagesAdminAPIViewSet does not scope its queryset through the page permission policy, bypassing page-level access controls entirely. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires a valid authenticated session with Wagtail admin panel access (PR:L per the CVSS vector - ordinary site visitors without admin credentials cannot exploit this vulnerability). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 score of 4.3 (AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N) is well-calibrated: the vulnerability is network-reachable and low-complexity, but strictly gated behind authenticated Wagtail admin access (PR:L), with no integrity or availability impact. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Upgrade to a patched Wagtail release corresponding to the installed branch: 7.0.9, 7.3.4, 7.4.3, or 8.0rc2. … Detailed patch versions, workarounds, and compensating controls in full report. |
