CVE-2024-46979: Data leak of notification filters of users in XWiki Platform
Impact
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.
Patches
The 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.
Workarounds
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 the same changes as in the patch. See c8c6545f9bde6f5aade994aa5b5903a67b5c2582.
