Authenticated privilege escalation via SQL injection
Published Mar 10, 2026 · Updated Mar 10, 2026
SQL injection in Microsoft SQL Server 2025 allows remote authenticated users to elevate privileges through a network connection. Microsoft has not disclosed the affected Database Engine routine or how it incorporates attacker-controlled input into an SQL command. Low-privileged SQL Server access is required, and successful exploitation elevates privileges within the database service.
