Summary
CVE-2026-58073 is a critical authentication bypass vulnerability in Veeam Service Provider Console (VSPC) that allows an unauthenticated, network-based attacker to impersonate a managed agent and obtain that agent’s credentials. Rated Critical with a CVSS v4.0 base score of 9.5, it affects VSPC 9.2.1.33875 and all earlier version 9 builds.
Technical details
- Root cause: Authentication bypass using an alternate path or channel (CWE-288) in the console’s agent management flow.
- Trigger conditions: No authentication is required; the attacker impersonates a managed agent to the console.
- Attack vector: Network (remote, unauthenticated).
- Impact: The attacker obtains the impersonated agent’s credentials, resulting in high impact to confidentiality, integrity, and availability. Because VSPC provides multi-tenant backup management for hosting and MSP environments, a compromised console can expose many downstream customers.
Affected software
- Veeam Service Provider Console 9.2.1.33875 and all earlier version 9 builds.
Severity
- CVSS v4.0 base score: 9.5 (Critical)
- CVSS v4.0 vector:
CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H
Mitigation and recommended actions
- Immediate: Upgrade Veeam Service Provider Console to version 9.3.0.35057 or later, which resolves this vulnerability.
- If no patch can be applied yet: No standalone workaround exists. Restrict network access to the console and its portal to trusted networks until patching is complete.
