A stored cross-site scripting (XSS) vulnerability exists on ModelAdmin views within the Wagtail admin interface.

A user with a limited-permission editor account for the Wagtail admin could potentially craft pages and documents that, when viewed by a user with higher privileges, could perform actions with that user's credentials.

The vulnerability is not exploitable by an ordinary site visitor without access to the Wagtail admin, and only affects sites with ModelAdmin enabled.

For page, the vulnerability is in the "Choose a parent page" ModelAdmin view, available when managing pages via ModelAdmin.

For documents, the vulnerability is in the ModelAdmin Inspect view when displaying document fields.

< 4.1.4

>= 4.2.0 lt 4.2.2

A memory exhaustion bug exists in Wagtail's handling of uploaded images and documents.

For both images and documents, files are loaded into memory during upload for additional processing.

A user with access to upload images or documents through the Wagtail admin interface could upload a file so large that it results in a crash or denial of service.

The vulnerability is not exploitable by an ordinary site visitor without access to the Wagtail admin.

It can only be exploited by admin users with permission to upload images or documents.

Image uploads are restricted to 10MB by default, however this validation only happens on the frontend and on the backend after the vulnerable code.
