CVE-2026-58073 is an authentication-bypass vulnerability in Veeam Service Provider Console (VSPC) 9.2.1.33875 and earlier version 9 builds. The agent-login logic checks whether a supplied managed-agent GUID exists in a process-global table of logged-in agents, rather than binding that login state to the certificate presented on the current connection. An unauthenticated peer able to reach the agent channel can impersonate a currently connected agent and invoke certificate issuance for that agent, obtaining its credentials, including an agent certificate bundle signed by the console’s Veeam agent root CA. VSPC 9.3.0 binds agent login validation to the certificate thumbprint recorded for the active agent connection.

A critical authentication/agent-impersonation flaw in Veeam Service Provider Console (VSPC). A self-signed certificate containing the GUID of a currently connected agent can bypass authorization due to login state being checked by GUID rather than the current connection certificate, enabling theft of a genuine VSPC-issued agent certificate.
An authentication/impersonation vulnerability in Veeam Service Provider Console that allows an unauthenticated attacker to impersonate a managed agent and obtain that agent's credentials.
