CWE-280
AllowedImproper Handling of Insufficient Permissions or Privileges
Abstraction: Base · Status: Draft
The product does not handle or incorrectly handles when it has insufficient privileges to access resources or functionality as specified by their permissions. This may cause it to follow unexpected code paths that may leave the product in an invalid state.
293 vulnerabilities reference this CWE, most recent first.
GHSA-3VRH-M9W7-V94F
Vulnerability from github – Published: 2026-08-20 18:42 – Updated: 2026-08-20 18:42Impact
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
Acknowledgements
Many thanks to xuliang@QAX for reporting this issue.

Mitigation MIT-46
Strategy: Separation of Privilege
- Compartmentalize the system to have "safe" areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area.
- Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
Mitigation
Always check to see if you have successfully accessed a resource or system functionality, and use proper error handling if it is unsuccessful. Do this even when you are operating in a highly privileged mode, because errors or environmental conditions might still cause a failure. For example, environments with highly granular permissions/privilege models, such as Windows or Linux capabilities, can cause unexpected failures.
