CVE-2023-37911Public exploitNetwork attack vector

Deleted-document disclosure via missing revision authorization

Published Oct 25, 2023 · Updated Sep 17, 2024

Authorization bypass in affected XWiki Platform releases allows remote authenticated users to read deleted document revisions over the network. The Document.getDocumentRevision and XWiki.getDocument revision paths retrieve deleted content without checking the current user's VIEW right on that revision. Exploitation requires view access to a re-created document, or edit access sufficient to re-create a deleted document, and exposes prior content without modifying it.
