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
console-io is a module that allows users to implement a web console in their application. A malicious user could bypass the authentication and execute any command that the user who is running the console-io application 2.2.13 and earlier is able to run. This means that if console-io was running from root, the attacker would have full access to the system. This vulnerability exists because the console-io application does not configure socket.io to require authentication, which allows a malicious user to connect via a websocket to send commands and receive the response.

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

console-io versions 2.2.13 and earlier fail to configure socket.io authentication, allowing unauthenticated websocket connections to send commands and receive responses. A remote attacker can execute arbitrary commands with the same privileges as the user running the console-io process.

MitigationConfigure socket.io to require authentication and ensure console-io does not run with elevated privileges (avoid running as root).

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 console-io installation and version
    Run 'npm list console-io' or inspect package.json dependencies to determine the installed version of console-io
    Affected if The installed version is 2.2.13 or earlier
  2. Locate console-io configuration files
    Search the application directory for configuration files related to socket.io or console-io setup, such as config.js, server.js, or any file that initializes the socket.io server
    Affected if No authentication middleware (such as 'io.use()' with an auth handler) is found in socket.io initialization code
  3. Verify socket.io authentication is enabled
    Examine the socket.io configuration code for authentication enforcement - look for any middleware, authentication callbacks, or token validation logic before allowing connections
    Affected if Socket.io accepts connections without requiring any authentication credentials
  4. Check the process execution context
    Inspect how the console-io process is launched - check the startup script, systemd service file, or process manager configuration to identify the user account running the console-io service
    Affected if Console-io runs as root or with elevated system privileges

If console-io version 2.2.13 or earlier is installed AND socket.io lacks authentication configuration AND the service runs with elevated privileges, the environment is vulnerable to remote command execution via unauthenticated websocket connections.

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.

dbcve · scoped
Upgrade available Upgrade to a release after 2.2.13
Interim mitigation

Configure socket.io to require authentication and ensure console-io does not run with elevated privileges (avoid running as root).

Recommended fix Moderate confidence

console-io > 2.2.13 (any version after 2.2.13 contains the fix)

  1. Update console-io to a version newer than 2.2.13 by running: npm install console-io@latest or npm update console-io
  2. Verify the authentication configuration is properly set after upgrade
  3. Restart the application to apply the changes
