KB5068406 is a High security update for Microsoft SQL Server 2017 for x64-base, released 2025-11-11. It closes 1 CVE with a maximum CVSS of 8.8. It is the fourth largest of the 18 updates Microsoft shipped that month, by CVEs closed.
Update summary
Fixes 1 CVE. Most severe CVSS 8.8 (High). EPSS exploit probability up to 1.1%. Among the lower half of tracked Microsoft updates by EPSS exploit probability.
A newer security update for Microsoft SQL Server 2017 for x64-based Systems (GDR) has shipped since this one: KB5101346 (2026-07-14). For cumulative update families the newer package includes these fixes, so installing that one is usually the shorter path. Verify against your own update rings before you skip this package.
KB5068406 is a November 2025 GDR update patching CVE-2025-59499 across SQL Server 2016 SP3, 2017, and 2019 on x64. The single flaw carries High severity (CVSS 8.8), which for a database engine typically points to a privilege escalation or injection path that lets an authenticated user gain elevated database access. EPSS is only 1 percent and it is not in CISA KEV, so this is a routine but worthwhile fix rather than an emergency.
Do this: Schedule the GDR update for your SQL Server 2016 SP3, 2017, and 2019 x64 instances during the next maintenance window, prioritizing servers that grant login access to lower-trust or application accounts.
