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 · unedited
KV Studio versions 12.23 and prior contain a stack-based buffer overflow vulnerability. If the product uses a specially crafted file, arbitrary code may be executed on the affected product.

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 · moderate confidence

KV Studio versions 12.23 and prior contain a stack-based buffer overflow vulnerability that can be triggered when processing a specially crafted file. This memory corruption issue allows an attacker to achieve arbitrary code execution on the affected system.

MitigationUpgrade KV Studio to a version greater than 12.23. Until then, avoid opening files from untrusted or unknown sources.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify KV Studio installation
    Check for KV Studio in your system: look in Program Files (Windows), Applications folder (Mac), or use command 'Get-ItemProperty' in PowerShell for Windows or 'ls /Applications' on Mac to locate the installed application
    Affected if KV Studio is installed on the system
  2. Determine installed KV Studio version
    Open KV Studio and navigate to Help > About, or right-click the application in your program list and select Properties to view the version number. On Windows, you can also run 'Get-ItemProperty' on the executable file
    Affected if The displayed version is 12.23 or any version number lower than 12.23
  3. Confirm file processing feature is in use
    The vulnerability triggers when processing a specially crafted file. Determine if KV Studio is actively used to open, import, or process project files, configuration files, or data files from any source
    Affected if KV Studio is used to process files and the installed version is 12.23 or prior
  4. Compare against affected version range
    Take the identified version number and compare it against the affected range: versions 12.23 and all prior versions (for example: 12.23, 12.22, 12.21, 12.0, any beta or release candidate versions below 12.23)
    Affected if Your installed version falls within 12.23 or lower

You are affected if KV Studio version 12.23 or lower is installed AND the software is used to process files, since the stack-based buffer overflow triggers during file processing of specially crafted files.
