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
The Node.js package browserstack-local 1.5.8 contains a command injection vulnerability. This occurs because the logfile variable is not properly sanitized in lib/Local.js.

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

The browserstack-local Node.js package version 1.5.8 contains a command injection vulnerability in lib/Local.js. The logfile variable is not properly sanitized before being used in system calls, allowing an attacker to inject arbitrary shell commands via specially crafted logfile input.

MitigationUsers should upgrade to a patched version of browserstack-local when available. Until then, avoid passing untrusted or user-controlled input to the logfile parameter, and validate/sanitize any logfile path before use.

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 if browserstack-local is installed
    Run `npm list browserstack-local` or check your package.json for the browserstack-local dependency
    Affected if The package is not present in the environment, then not affected
  2. Verify the installed version
    Check the version number returned by `npm list browserstack-local` or look at the version in package.json
    Affected if The version is NOT exactly 1.5.8, then not affected (only version 1.5.8 is vulnerable)
  3. Locate the vulnerable library file
    Check for the presence of lib/Local.js within the browserstack-local package directory (typically in node_modules/browserstack-local/lib/Local.js)
    Affected if The file does not exist, then not affected
  4. Determine if the logfile parameter is used
    Search codebase for instances where the Local constructor or start method is called with a logfile option, or review configuration files for logfile settings passed to browserstack-local
    Affected if The logfile parameter is not being used or configured, the command injection cannot be triggered

You are affected only if browserstack-local version 1.5.8 is installed AND the logfile parameter is being used in your configuration or code.

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.
