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
A security vulnerability has been detected in MoussaabBadla code-screenshot-mcp up to 0.1.0. This affects an unknown part of the component HTTP Interface. Such manipulation leads to os command injection. It is possible to launch the attack remotely. The exploit has been disclosed publicly and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

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

OS command injection vulnerability in the HTTP interface of code-screenshot-mcp up to version 0.1.0. An attacker can manipulate input to the HTTP interface to execute arbitrary operating system commands remotely.

MitigationImplement strict input validation and sanitization on all user-supplied parameters before passing them to system calls. Use parameterized APIs or whitelisting instead of passing unsanitized input to shell commands.

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 installed package version
    Run 'npm list code-screenshot-mcp' or check package.json for the code-screenshot-mcp dependency version
    Affected if The installed version is 0.1.0 or earlier (versions prior to the fix contain the command injection flaw)
  2. Confirm HTTP interface is exposed
    Inspect application configuration files and running processes to determine if the HTTP server component of code-screenshot-mcp is enabled and accessible on a network interface
    Affected if The HTTP interface is enabled and reachable from network locations where untrusted input could be submitted
  3. Check for unsanitized input pathways
    Review application logs or network traffic for requests to the code-screenshot-mcp endpoint that contain shell metacharacters (such as |, ;, &, $`, $(...), or backticks) in parameters
    Affected if The application accepts and processes shell metacharacters without sanitization through its HTTP interface

A user is affected if code-screenshot-mcp version 0.1.0 or earlier is installed with its HTTP interface enabled and accessible, allowing unsanitized user input to reach command execution logic.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
