CVE-2026-58070

Credential disclosure via cleartext guest support logging

Published Aug 26, 2026 · Updated Aug 27, 2026

Credential exposure in Veeam Backup & Replication 13.0.2.29 and earlier 13.x builds allows local users to recover guest OS credentials. The Application-Aware Processing workflow writes the guest processing account's credentials in cleartext to a support log on the processed guest. Exploitation requires read access to that guest log and exposes privileged account credentials without altering data or interrupting service.
