CVE-2026-21667: Vulnerability in Veeam Backup and ReplicationCVE-2026-21667 0 CVE-2026-21667 is a critical vulnerability in Veeam Backup and Replication that allows an authenticated domain user to execute remote code on the Backup Server without user interaction. The flaw stems from improper access control (CWE-284), enabling privilege escalation and full system compromise. With a CVSS score of 10.0, this vulnerability impacts confidentiality, integrity, and availability severely. Although no known exploits are currently in the wild, the ease of exploitation and the critical nature of backup infrastructure make this a high-risk threat. Organizations relying on Veeam Backup and Replication should prioritize patching once available and implement strict access controls. Countries with significant Veeam market penetration and critical infrastructure reliance on backup solutions are at heightened risk. Immediate mitigation steps include restricting domain user permissions, monitoring for suspicious activity, and isolating backup servers from unnecessary network exposure.
