Authenticated file disclosure via Cloud Connect

Published Oct 7, 2026 · Updated Oct 7, 2026

File disclosure in Veeam Backup & Replication 12 and 13 allows remote authenticated users to read files on a Cloud Connect provider host. The tenant-to-provider request path exposes host files, but Veeam has not published the specific handler or input-validation failure. Exploitation requires a Cloud Connect tenant account and a Windows-based provider server; the documented impact is file reading, not modification.
