CVE-2026-3094
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedDelta Electronics CNCSoft-G2 lacks proper validation of the user-supplied file. If a user opens a malicious file, an attacker can leverage this vulnerability to execute code in the context of the current process.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceDelta Electronics CNCSoft-G2 contains a file validation vulnerability where the application fails to properly validate user-supplied file data before processing. An attacker can craft a malicious file that, when opened by a user, allows arbitrary code execution within the context of the application's process.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify if CNCSoft-G2 is installedCheck system for Deltaww CNCSoft-G2 application - look in Program Files, Program Files (x86), or the vendor's default installation directory. Use 'Get-ItemProperty' in PowerShell or check Add/Remove Programs.Affected if The software is present on the system
-
Determine the installed versionLocate the CNCSoft-G2 executable (typically named CNCSoft-G2.exe or similar) and check its version property. Right-click the executable, select Properties, then Details. Or use PowerShell: (Get-Item 'C:\Program Files\Delta Electronics\CNCSoft-G2\CNCSoft-G2.exe').VersionInfo.FileVersionAffected if The version number is lower than 2.1.0.39
-
Verify file handling functionality existsConfirm the application has file open/import capabilities - check if the application UI includes File > Open, Import, or similar menu options for loading project or configuration files.Affected if File open/import functionality is present and accessible to users
-
Check for custom file associationsReview what file extensions the application is configured to open by default. Check registry under HKCR\. extensions or look for file type associations in the application documentation or settings.Affected if The application processes user-supplied files through its file handling features
You are affected if Deltaww CNCSoft-G2 is installed with a version lower than 2.1.0.39 and users can open or import files within the application.
