CVE-2025-49586Public exploitNetwork attack vector

Authenticated code execution via unsafe XClass preview

Published Jun 13, 2025 · Updated Jun 13, 2025

Incorrect authorization in affected XWiki Platform releases allows remote authenticated users with AWM edit rights to execute server-side code. PropertyClass.displayCustom previews an edited XClass with the persisted class document's author and restriction context instead of the edited owner document's context. Editing one App Within Minutes application, a right granted to all users by default, is sufficient to gain programming rights and execute code on the server.
