macro-pdfviewer is a PDF Viewer Macro for XWiki using Mozilla pdf.js. The PDF Viewer macro allows an attacker to view any attachment using the "Delegate my view right" feature as long as the attacker can view a page whose last author has access to the attachment. For this, the attacker only needs to provide the reference to a PDF file to the macro. To obtain the reference of the desired attachment, the attacker can access the Page Index, Attachments tab. Even if the UI shows N/A, the user can inspect the page and check the HTTP request that fetches the live data entries. The attachment URL is available in the returned JSON for all attachments, including protected ones and allows getting the necessary values. This vulnerability is fixed in version 2.5.6.

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. It's possible to get access to notification filters of any user by using a URL such as `<hostname>xwiki/bin/get/XWiki/Notifications/Code/NotificationFilterPreferenceLivetableResults?outputSyntax=plain&type=custom&user=<username>`. This vulnerability impacts all versions of XWiki since 13.2-rc-1. The filters do not provide much information (they mainly contain references which are public data in XWiki), though some info could be used in combination with other vulnerabilities. This vulnerability has been patched in XWiki 14.10.21, 15.5.5, 15.10.1, 16.0RC1. The patch consists in checking the rights of the user when sending the data. Users are advised to upgrade. It's possible to workaround the vulnerability by applying manually the patch: it's possible for an administrator to edit directly the document `XWiki.Notifications.Code.NotificationFilterPreferenceLivetableResults` to apply t…

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. It's possible for any user knowing the ID of a notification filter preference of another user, to enable/disable it or even delete it. The impact is that the target user might start loosing notifications on some pages because of this. This vulnerability is present in XWiki since 13.2-rc-1. This vulnerability has been patched in XWiki 14.10.21, 15.5.5, 15.10.1, 16.0-rc-1. The patch consists in checking properly the rights of the user before performing any action on the filters. Users are advised to upgrade. It's possible to fix manually the vulnerability by editing the document `XWiki.Notifications.Code.NotificationPreferenceService` to apply the changes performed in commit e8acc9d8e6af7dfbfe70716ded431642ae4a6dd4.

XWiki Platform is a generic wiki platform. The REST API exposes the history of any page in XWiki of which the attacker knows the name. The exposed information includes for each modification of the page the time of the modification, the version number, the author of the modification (both username and displayed name) and the version comment. This information is exposed regardless of the rights setup, and even when the wiki is configured to be fully private. On a private wiki, this can be tested by accessing /xwiki/rest/wikis/xwiki/spaces/Main/pages/WebHome/history, if this shows the history of the main page then the installation is vulnerable. This has been patched in XWiki 15.10.9 and XWiki 16.3.0RC1.

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. A user without script/programming right can trick a user with elevated rights to edit a content with a malicious payload using a WYSIWYG editor. The user with elevated rights is not warned beforehand that they are going to edit possibly dangerous content. The payload is executed at edit time. This vulnerability has been patched in XWiki 15.10RC1.

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. It is possible for a user without Script or Programming rights to craft a URL pointing to a page with arbitrary JavaScript. This requires social engineer to trick a user to follow the URL. This has been patched in XWiki 14.10.21, 15.5.5, 15.10.6 and 16.0.0.

Pro Macros provides XWiki rendering macros. Missing escaping in the Viewpdf macro allows any user with view right on the `CKEditor.HTMLConverter` page or edit or comment right on any page to perform remote code execution. Other macros like Viewppt are vulnerable to the same kind of attack. This vulnerability is fixed in 1.10.1.

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. By creating a conflict when another user with more rights is currently editing a page, it is possible to execute JavaScript snippets on the side of the other user, which compromises the confidentiality, integrity and availability of the whole XWiki installation. This has been patched in XWiki 15.10.8 and 16.3.0RC1.

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. Any user with edit right on any page can perform arbitrary remote code execution by adding instances of `XWiki.SearchSuggestConfig` and `XWiki.SearchSuggestSourceClass` to their user profile or any other page. This compromises the confidentiality, integrity and availability of the whole XWiki installation. This vulnerability has been patched in XWiki 14.10.21, 15.5.5 and 15.10.2.

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. When uploading an attachment with a malicious filename, malicious JavaScript code could be executed. This requires a social engineering attack to get the victim into uploading a file with a malicious name. The malicious code is solely executed during the upload and affects only the user uploading the attachment. While this allows performing actions in the name of that user, it seems unlikely that a user wouldn't notice the malicious filename while uploading the attachment. This has been patched in XWiki 14.10.21, 15.5.5, 15.10.6 and 16.0.0.
