CVE-2024-21648Network attack vector

Privilege escalation via unchecked page rollback

Published Jan 8, 2024 · Updated Jun 17, 2025

Improper privilege handling in XWiki Platform allows remote authenticated users to regain page rights through a rollback action. RollbackAction previously invoked XWiki.rollback without marking the operation as user-triggered, so checkSavingDocument did not verify permission to save the restored revision. Exploitation requires rollback access and an earlier page revision containing rights no longer held, and it restores that revision's content and permissions.
