Summary: XWiki Platform vulnerable to persistent Cross-site Scripting through CKEditor Configuration pages

Details: ### Effect Any user with edit rights can edit all pages in the `CKEditor' space. This makes it possible to perform a variety of harmful actions, such as - removing technical documents, leading to loss of service - Editing the javascript configuration of CKEditor, leading to persistent XSS ### Patches 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. ### Workarounds The issue can be fixed manually 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.
