Microsoft SQL Server 2017 (GDR): Improper Neutralization of Special Elements used in a Command
CVE-2026-116930 is a high-severity improper neutralization of special elements used in a command vulnerability in Microsoft SQL Server 2017 (GDR) from Microsoft, with a CVSS 3.1 base score of 8.8 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, but only if a user takes part, for example by opening a link or file. The record lists version 14.0.2150.2 as the first without the flaw, so updating Microsoft SQL Server 2017 (GDR) to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.92% chance of exploitation within 30 days, higher than 61% of scored CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update Microsoft SQL Server 2017 (GDR) to 14.0.2150.2 or a later version.
- Update Microsoft SQL Server 2017 for x64-based Systems (CU31) to 14.0.3570.2 or a later version.
- Update Microsoft SQL Server 2019 (GDR) to 15.0.2210.4 or a later version.
- Read the advisory on msrc.microsoft.com for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.
- Because the attack needs a user to take part, warn users about unexpected links and files related to this product until it is patched.

Official description
Improper neutralization of special elements used in a command ('command injection') in SQL Server allows an unauthorized attacker to execute code over a network.
Source: the CVE record as published by its numbering authority, via NVD and CVE.org.
The underlying weakness: Improper Neutralization of Special Elements used in a Command
The product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component.
How developers prevent this class of flaw
- If at all possible, use library calls rather than external processes to recreate the desired functionality.
- If possible, ensure that all external commands called from the program are statically created.
- Run time: Run time policy enforcement may be used in an allowlist fashion to prevent use of any non-sanctioned commands.
