Technical details
The vulnerability is an improper privilege/permission restriction (CWE-280) in Wagtail's Admin API "copy for translation" endpoint. A CMS user possessing the "submit translations" permission can exploit this endpoint to copy pages that they lack edit access to, bypassing intended authorization checks and viewing restricted page contents. The attack requires low privileges (only "submit translations" permission) and network access to the API endpoint, with no user interaction needed. An attacker can achieve unauthorized read access to confidential page data. Patches are available in Wagtail 7.0.9, 7.3.4, 7.4.3, and 8.0rc2 and later.
