Wagtail vulnerabilities

Wagtail's internal Pages admin API returns page fields declared in api_fields without sufficient access control, allowing users with admin access to retrieve restricted draft and live content. Fixed in versions 7.0.9, 7.3.4, 7.4.3, and 8.0rc2.

In Wagtail, a Django-based CMS, versions prior to 7.0.8, 7.3.3, and 7.4.2 contain a reflected XSS vulnerability in the dynamic image URL generator view within the admin interface. A low-privileged editor can craft a malicious URL that, when viewed by an admin, executes actions with admin credentials.

In Wagtail, an open source content management system built on Django, versions prior to 7.0.8, 7.3.3, and 7.4.2 allow a low-level user with the 'Can submit translation' permission to create translations for any page, including those they do not have permissions for. This issue has been fixed in versions 7.0.8, 7.3.3, and 7.4.2.

In Wagtail, an open source CMS built on Django, a missing permission check on the image preview endpoint allows users with Wagtail admin access to preview any image. The existing data of the image object itself is not exposed. The vulnerability is not exploitable by ordinary site visitors without admin access.

In Wagtail, an open source CMS built on Django, versions prior to 7.0.8, 7.3.3, and 7.4.2 allow an authenticated admin user to trigger expensive rendition processing with crafted filter specs, potentially causing service degradation. The vulnerability is not exploitable by ordinary site visitors without Wagtail admin access.

In Wagtail, an open source CMS built on Django, versions prior to 7.0.8, 7.3.3, and 7.4.2, the Documents and Images chooser's chosen endpoint incorrectly listed items for which the user has not been granted choose permission. A user with access to the Wagtail admin could see the filename, name, and URLs of documents and images in those collections.
