Senserva AI Opinion for KB5068401
KB5068401 patches CVE-2025-59499, a High severity SQL injection flaw (CVSS 8.8) in the GDR branches of SQL Server 2016 SP3, 2017, and 2019 on x64 systems. Anyone running these older SQL Server versions on x64 hardware is exposed, though the EPSS is only 1% and it is not in CISA KEV nor ransomware-linked. The 8.8 score reflects that an attacker with limited privileges could escalate through crafted queries, so multi-tenant or application-facing databases are the real concern.
Do this: Identify SQL Server 2016 SP3, 2017, and 2019 x64 instances on the GDR servicing branch and schedule KB5068401 during your next maintenance window, prioritizing databases exposed to untrusted input.
