CVE-2026-125106 PUBLISHED

Wagtail is an open source content management system built on Django. Prior to 7.0.9, 7.3.4, 7.4.3, and 8.0rc2, a Wagtail CMS user with the submit translations permission can call the Admin API copy for translation action for a source page that the user cannot edit. The action copies the inaccessible page into a translation, allowing the user to view its contents despite the missing source-page edit permission. This issue is fixed in versions 7.0.9, 7.3.4, 7.4.3, and 8.0rc2.
