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
An OS command injection vulnerability in the /stream-to-vlc Express route in hitarth-gg Zenshin before 2.7.0 allows remote attackers to execute arbitrary commands via the url parameter.

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 confidence

The /stream-to-vlc Express route in hitarth-gg Zenshin versions before 2.7.0 contains an OS command injection vulnerability in the 'url' parameter, allowing remote attackers to execute arbitrary operating system commands on the host.

MitigationUpgrade to Zenshin version 2.7.0 or later. If immediate patching is not possible, disable the /stream-to-vlc endpoint and implement strict input validation on the 'url' parameter to prevent shell metacharacter injection.

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. Confirm Zenshin is installed
    Identify if the hitarth-gg Zenshin application is running in your environment by checking running processes, installed packages, or application directories. Look for the application name 'Zenshin' or related files.
    Affected if Zenshin software is present on the system
  2. Check installed Zenshin version
    Retrieve the version of Zenshin currently installed. This may be in a package.json file, package-lock.json, a version file, or obtainable via a version command if the application exposes one. Compare the version number to the affected range (versions prior to 2.7.0).
    Affected if The installed version is less than 2.7.0 (e.g., 2.6.x, 2.5.x, etc.)
  3. Verify /stream-to-vlc endpoint exists
    Inspect the application source code, routing configuration, or API documentation to confirm the /stream-to-vlc route is defined in the Express application. Alternatively, attempt an HTTP request to this endpoint if it may be externally accessible.
    Affected if The /stream-to-vlc endpoint is defined and accessible in the application
  4. Confirm url parameter handling
    Review the source code implementation of the /stream-to-vlc route handler. Look for code that takes a 'url' query parameter and passes it to system command execution functions (such as exec, execSync, spawn, or shell execution) without sanitization.
    Affected if The url parameter is passed directly to system command functions without input validation

You are affected if Zenshin version is less than 2.7.0 AND the /stream-to-vlc endpoint exists with unsanitized url parameter handling in your deployment.

Interim mitigation

Upgrade to Zenshin version 2.7.0 or later. If immediate patching is not possible, disable the /stream-to-vlc endpoint and implement strict input validation on the 'url' parameter to prevent shell metacharacter injection.

Recommended fix Moderate confidence

Upgrade to Zenshin version 2.7.0 or later

  1. 1. Identify the current version of Zenshin being used (check package.json or package-lock.json)
  2. 2. Upgrade to version 2.7.0 or later using: npm install zenshin@latest or npm install zenshin@^2.7.0
  3. 3. Verify the upgrade was successful by checking the installed version: npm list zenshin
  4. 4. Restart the application to load the patched version
  5. 5. Test that the /stream-to-vlc route no longer accepts arbitrary command injection via the url parameter
