Veeam releases security updates to address a critical vulnerability in its Backup & Replication software that could allow remote code execution (RCE) on backup servers. Multiple outlets report that the issue is tracked as CVE-2026-44963 and is rated with a CVSS score of 9.4 out of 10.0. According to Veeam’s advisory language cited in the reports, the flaw can be exploited by an authenticated domain user to achieve RCE on a Backup Server when the server is domain-joined. The updates are intended to eliminate the risk by patching the affected components of Veeam Backup & Replication. The reports indicate the problem is serious because it involves code execution rather than denial of service or information disclosure, and because exploitation requires authenticated access within a domain environment. Organizations using Veeam Backup & Replication are advised to apply the released patches to mitigate potential exploitation.
