Wagtail: Improper restriction handling on Pages admin API
빠른 조치
GHSA-3vrh-m9w7-v94f — wagtail: 아래 명령으로 수정 버전으로 올리세요.
pip install --upgrade 'wagtail>=7.0.9'상세
### Impact
The internal Pages admin [API](https://docs.wagtail.org/en/stable/advanced_topics/api/index.html) 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:
```python # 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 ```
