Network-reachable SQL injection needing only a low-privileged login (PR:L) and no user interaction; privilege elevation yields high C/I/A within the unchanged scope of the database server.

Improper neutralization of special elements used in an sql command ('sql injection') in SQL Server allows an authorized attacker to elevate privileges over a network.
AnalysisAI
Privilege elevation in Microsoft SQL Server (2016 SP3 through 2025) allows an authenticated attacker to inject crafted SQL commands over the network and gain higher database privileges (CVSS 8.8). The flaw is a classic improper neutralization of special elements (CWE-89) reachable by any principal already holding low-level database access. No public exploit has been identified at time of analysis, and it is not listed in CISA KEV, though a vendor patch is available.
Technical ContextAI
The vulnerability is a SQL injection (CWE-89) in Microsoft SQL Server, Microsoft's relational database management system used across enterprise, cloud (Azure Connect Feature Pack), and application-backend deployments. The CPE data confirms the affected engine spans SQL Server 2016 Service Pack 3 (GDR and Azure Connect Feature Pack), 2017 (GDR and CU 31), 2019 (GDR and CU 32), 2022 (GDR and CU 25), and 2025 (GDR and CU 6). Improper neutralization means user-controllable input reaches a SQL command context without adequate sanitization or parameterization, letting an attacker break out of the intended query and execute attacker-chosen SQL - here leveraged not for pure data theft but to elevate the effective privileges of the connecting principal within the server.
RemediationAI
Apply the vendor-released security update for your specific SQL Server branch as tracked in the Microsoft MSRC update guide (https://msrc.microsoft.com/update-guide/vulnerability/CVE-2026-47295); Patch available per vendor advisory covers SQL Server 2016 SP3 (GDR and Azure Connect Feature Pack), 2017 (GDR/CU 31), 2019 (GDR/CU 32), 2022 (GDR/CU 25), and 2025 (GDR/CU 6) - select the GDR or CU package matching your current servicing train and install the corresponding fixed build. Because exploitation requires an authenticated (PR:L) principal, compensating controls until patching include tightening database logins to least privilege and revoking unnecessary accounts, restricting network reachability of the SQL Server port (default TCP 1433) to trusted application hosts via firewall rules, and enabling query auditing/monitoring for anomalous statements; note these reduce but do not eliminate risk from a legitimate low-privileged account and may disrupt applications that rely on broad connectivity.
