Description
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.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.xwiki.platform:xwiki-platform-livetable-ui, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update org.xwiki.platform:xwiki-platform-livetable-ui to 16.10.17 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-48048 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
