CVE-2026-58071 is a missing-authentication vulnerability in Veeam Service Provider Console affecting versions earlier than 9.3, including version 9.2.1.33875 and earlier version 9 builds. The flaw allows an unauthenticated attacker to access the proxied appliance API with Portal Administrator privileges during a narrow time window immediately after a legitimate administrator session begins. The issue is consistent with insufficient session management and access control around a critical administrative function, resulting in temporary exposure of privileged API access without authentication.
