CVE-2025-46554Public exploitNetwork attack vector

Attachment metadata disclosure via missing per-item authorization

Published Apr 30, 2025 · Updated Apr 30, 2025

Missing authorization in XWiki Platform's wiki attachment REST endpoint allows remote attackers to read restricted attachment metadata. BaseAttachmentsResource.getAttachments converts every query result without checking VIEW rights on each attachment reference. No authentication or user interaction is required, so even a private wiki can disclose attachment-list metadata, while the advisory reports no file-content access.
