CVE-2025-29926Network attack vector

Unauthenticated wiki creation via missing authorization check

Published Mar 19, 2025 · Updated Mar 19, 2025

Improper authorization in affected XWiki Platform releases allows remote attackers to create wikis through the WikiManager REST API. DefaultWikiManagerREST.createWiki processes POST requests without checking the caller's CREATE_WIKI right. The optional REST module must be installed; unauthenticated callers can become administrators of created wikis and use that access to attack the wider farm.
