CVE-2022-31190Network attack vector

Withdrawn-item metadata disclosure via missing read authorization

Published Aug 1, 2022 · Updated Apr 23, 2025

Incorrect authorization in DSpace XMLUI 4.0 through 6.3 allows remote attackers to read withdrawn-item metadata through mets.xml. DSpaceMETSGenerator renders the METS document without first checking whether the ItemAdapter grants the current context READ permission. Knowing a withdrawn item's handle or URL is sufficient; exposure is limited to its metadata and does not affect JSPUI or DSpace 7.x.
