Authenticated privilege escalation over a network
Published Mar 10, 2026 · Updated Mar 10, 2026
Improper input validation in Microsoft SQL Server allows remote authenticated users to elevate privileges through a network connection. Microsoft has not published the affected component, accepted input type, or validation operation. The attacker must already hold SQL Server credentials; Microsoft identifies privilege elevation but does not disclose the resulting role or execution context.
