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
windows-seleniumjar-mirror downloads the Selenium Jar file windows-seleniumjar-mirror downloads binary resources over HTTP, which leaves it vulnerable to MITM attacks. It may be possible to cause remote code execution (RCE) by swapping out the requested resources with an attacker controlled copy if the attacker is on the network or positioned in between the user and the remote server.

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 windows-seleniumjar-mirror npm package downloads Selenium JAR binary resources over unencrypted HTTP instead of HTTPS, allowing man-in-the-middle attackers to intercept and replace the downloaded files with malicious equivalents. Since the JAR is executed as part of Selenium automation, a compromised download could enable remote code execution on the victim's machine.

MitigationReplace all HTTP download URLs with HTTPS equivalents and implement checksum verification to ensure downloaded binaries match expected values. Publish an updated package version and notify users to upgrade immediately.

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 if windows-seleniumjar-mirror package is installed
    Run 'npm list windows-seleniumjar-mirror' or check package.json for this dependency
    Affected if The package appears in installed dependencies or package.json
  2. Identify installed package version
    Run 'npm list windows-seleniumjar-mirror --depth=0' to see the installed version number
    Affected if Installed version is 2.52.1 or lower
  3. Inspect download source URLs in package code
    Examine the package's source files (typically in node_modules/windows-seleniumjar-mirror) for HTTP URLs used to fetch Selenium JAR files
    Affected if Code contains HTTP:// URLs instead of HTTPS:// for downloading binaries
  4. Verify if downloads have occurred
    Check local filesystem for any Selenium JAR files that may have been downloaded by this package
    Affected if JAR files exist and were obtained via unencrypted HTTP connections

User is affected if windows-seleniumjar-mirror version 2.52.1 or lower is installed and the package uses HTTP URLs to download Selenium JAR binaries.

Upgrade available Upgrade to a release after 2.52.1
Interim mitigation

Replace all HTTP download URLs with HTTPS equivalents and implement checksum verification to ensure downloaded binaries match expected values. Publish an updated package version and notify users to upgrade immediately.
