CVE-2026-55468

Wagtail: Improper restriction handling on Pages admin API

# 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

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.

CVE-2026-55468 has a CVSS score of 4.3 (Medium). The vector is network-reachable, low privileges required, and no user interaction. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (7.0.9, 7.3.4, 7.4.3, 8.0rc2); upgrading removes the vulnerable code path.

5. Is CVE-2026-55468 exploitable, and should I be worried? Whether CVE-2026-55468 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

6. What actually determines whether CVE-2026-55468 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.

   • Upgrade wagtail to 7.0.9 or later
   • Upgrade wagtail to 7.3.4 or later
   • Upgrade wagtail to 7.4.3 or later
