CVE-2026-50468 · Severity: medium · CVSS 6.5 · Published 2026-07-14

Microsoft SQL Server, a widely used database management system, contains a vulnerability that could allow an authorized user to access sensitive information they are not supposed to see. An attacker with basic login credentials could exploit this flaw over the network to read data from the server's memory. This could lead to the exposure of confidential business data or internal system information, potentially aiding further attacks.

## Technical details

A buffer over-read vulnerability (CWE-126) exists in Microsoft SQL Server 2025. The flaw is triggered when the application reads beyond the end of an intended buffer, allowing an attacker to access adjacent memory contents. An attacker must be authenticated to the SQL Server instance (Low Privileges) to exploit this vulnerability over the network. Successful exploitation results in unauthorized information disclosure, though it does not provide a mechanism for data modification or service disruption. Microsoft has released security updates to address this issue across affected versions.
