Risk summary
Senserva AI Opinion for CVE-2024-26191
CVE-2024-26191 is a High severity (CVSS 8.8) remote code execution flaw in the SQL Server Native Scoring feature, affecting SQL Server 2017 and 2019 on x64 systems including GDR and CU 31 branches. Because Native Scoring runs machine learning model predictions inside the database engine, exposure is highest where SQL Server hosts predictive scoring workloads reachable by lower privileged users. EPSS estimates only a 2 percent exploit probability and it is not in CISA KEV, so this is a patch on your normal cycle rather than an emergency.
Do this: Apply the current GDR or CU security update to your SQL Server 2017 and 2019 x64 instances, prioritizing any that expose Native Scoring or PREDICT functionality.
