Vulnerability in Xwiki Xwiki-Platform

CVE-2026-48048

XWiki Platform is a generic wiki platform. XWiki discovered that the patch for GHSA-5cf8-vrr8-8hjm was insufficient. Starting with version 6.2.1 and prior to versions 18.0.0RC1, 17.10.13, 17.4.9 and 16.10.17, with slightly modified parameters to the `LiveTableResults`, it is still possible to discover password hashes one bit at a time, so with 768 requests, the full password salt and hash can be retrieved of a user. The check for password (and email properties) has been adjusted in XWiki 18.0.0RC1, 17.10.13, 17.4.9 and 16.10.17. As a workaround, the patch can be applied manually to the wiki page `XWiki.LiveTableResultsMacros`.
