CVE-2026-64630Network attack vector

Cross-scope report data disclosure via authorization bypass

Published Aug 4, 2026 · Updated Aug 4, 2026

Incorrect authorization in Veeam ONE 13.0.2 and earlier version 13 builds allows remote authenticated users to read out-of-scope report data. Veeam has not disclosed the affected endpoint or exact missing authorization check; published material states only that retrieval escapes the shared link's report scope. A low-privileged account and a shared report link are required, and exposure is limited to report data beyond that link's intended scope.
