XWiki Improper Neutralization of Input During Web Page Generation (Cross-site Scripting) Vulnerability - CVE-2023-36477
XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. Any user with edit rights can edit all pages in the CKEditor39 space. This makes it possible to perform a variety of harmful actions such as removing technical documents leading to loss of service and editing the javascript configuration of CKEditor leading to persistent XSS. This issue has been patched in XWiki 14.10.6 and XWiki 15.1. This issue has been patched on the CKEditor Integration extension 1.64.9 for XWiki version older than 14.6RC1. Users are advised to upgrade. Users unable to upgrade may manually address the issue by restricting the edit and delete rights to a trusted user or group (e.g. the XWiki.XWikiAdminGroup group) implicitly disabling those rights for all other users. See commit 9d9d86179 for details.
