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
opencv.js was a malicious module published with the intent to hijack environment variables. It has been unpublished by npm.

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

opencv.js was a malicious npm package designed to hijack environment variables by exfiltrating them to an attacker-controlled endpoint. The package masqueraded as a legitimate OpenCV JavaScript binding but contained code to harvest sensitive environment data such as API keys, credentials, and configuration values.

MitigationImmediately audit dependency trees for opencv.js and remove it if present. Investigate any exposed environment variables for potential compromise and rotate all secrets that may have been exfiltrated.

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. Check package.json dependencies
    Search your package.json file for 'opencv.js' in the dependencies, devDependencies, or any other dependency fields
    Affected if The package is listed as a dependency
  2. Inspect node_modules directory
    Check if a directory named 'opencv.js' exists in your node_modules folder
    Affected if The directory exists in node_modules
  3. Query npm for installed packages
    Run 'npm list opencv.js' to see if the package is installed in your project
    Affected if The command returns any version of opencv.js
  4. Verify package source
    Check package-lock.json or yarn.lock for the opencv.js package entry and verify its source repository
    Affected if The package is present in lock files

If the opencv.js package is present in your dependency tree in any form, your environment has been compromised as the package is malicious and exfiltrates environment variables to an attacker.

Generated from the published advisory. Verify against your own configuration.

Check your environment

Paste your version and any relevant configuration and it will be compared against the affected criteria above. Do not include secrets or credentials.
