Senserva AI Opinion for CVE-2026-33120

CVE-2026-33120 is a remote code execution flaw in Microsoft SQL Server 2022 for x64-based systems shipping in the GDR branch, rated High severity with a CVSS score of 8.8. The 8.8 vector points to an authenticated database user being able to run code on the server host, so any SQL Server 2022 instance where login access extends beyond trusted admins is exposed. EPSS puts exploit probability at 1 percent and it is not in CISA KEV or tied to ransomware, so this is patch-on-schedule rather than emergency.

Do this: Apply the GDR update to your SQL Server 2022 x64 instances and confirm you are on the GDR branch rather than CU before scheduling the maintenance window.
