CVE-2026-47295: Microsoft SQL Server privilege escalation via SQL injection

CVE-2026-47295 · Severity: high · CVSS 8.8 · Published 2026-07-14

Microsoft SQL Server, a widely used database management system, is vulnerable to a security flaw that allows an authorized user to gain higher levels of access than they should have. By exploiting this vulnerability, an attacker with basic login credentials could potentially view, modify, or delete sensitive data across the entire database server. This could lead to significant data breaches or disruption of business operations.

Technologies: Microsoft Sql Server 2016, Microsoft Sql Server 2017, Microsoft Sql Server 2019, Microsoft Sql Server 2022. Vendors: Microsoft.

Technical details

A vulnerability exists in Microsoft SQL Server due to improper neutralization of special elements used in an SQL command (CWE-89). An authenticated attacker with low privileges can exploit this SQL injection vulnerability over a network connection without requiring user interaction. Successful exploitation allows the attacker to elevate their privileges, potentially gaining full control over the database instance (Confidentiality, Integrity, and Availability impact). The vulnerability affects multiple versions including SQL Server 2016, 2017, 2019, 2022, and 2025. Microsoft has released security updates to address this issue.
