CVE-2025-46557Network attack vector

Authentication disruption via unrestricted authenticator switching

Published Apr 30, 2025 · Updated Apr 30, 2025

Missing authorization in the authenticator administration page in XWiki Platform allows remote attackers to change the active authenticator. The XWiki.Authentication space lacked WebPreferences restricting page viewing and administrative actions to XWiki.XWikiAdminGroup. The page is viewable by default, but impact requires an alternative authenticator and no xwiki.cfg override; switching from SSO can interrupt authentication.
