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
mystem-fix is a node.js wrapper for MyStem morphology text analyzer by Yandex.ru mystem-fix 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 mystem-fix npm package downloads binary resources over HTTP instead of HTTPS, allowing a Man-in-the-Middle attacker to intercept the connection and substitute malicious content. Since the package executes these downloaded binaries, an attacker could achieve remote code execution by serving a compromised binary.

MitigationReplace HTTP URLs with HTTPS in the download mechanism and verify the integrity of the remote binary resources before execution. Consider using checksums or signatures to validate downloaded content.

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. Locate mystem-fix package in node_modules
    Run 'npm list mystem-fix' or search for 'mystem-fix' directory under node_modules
    Affected if The package is present in the project dependencies
  2. Check installed version
    Run 'npm list mystem-fix --depth=0' to see the installed version number
    Affected if Installed version is 0.0.5 or lower (any version <= 0.0.5)
  3. Inspect download source code
    Open the main entry file in node_modules/mystem-fix and search for HTTP URLs in download/fetch functions (look for http:// prefix, request, wget, curl calls)
    Affected if Code contains HTTP URLs (not HTTPS) for downloading binary resources
  4. Verify package is executed in your code
    Search project source for require('mystem-fix') or import statements referencing mystem-fix
    Affected if Your code imports or requires the mystem-fix package

You are affected if mystem-fix version 0.0.5 or lower is installed AND your code uses the package, which then downloads binaries over insecure HTTP URLs.

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.

From vendor data
Upgrade available Upgrade to a release after 0.0.5
Interim mitigation

Replace HTTP URLs with HTTPS in the download mechanism and verify the integrity of the remote binary resources before execution. Consider using checksums or signatures to validate downloaded content.
