CVE-2024-34506Network attack vector

Authenticated denial of service via unbounded subpage processing

Published May 5, 2024 · Updated Nov 4, 2025

Denial of service in MediaWiki 1.41.x before 1.41.1 allows remote authenticated users to hang requests through Special:MovePage. SpecialMovePage.php processes a page containing tens of thousands of subpages without bounding the request work, causing maximum request-time exhaustion. The user must hold page-move rights and select an exceptionally large subpage tree; the documented consequence is request interruption.
