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
A vulnerability was found in agentUniverse up to 0.0.18 and classified as critical. This issue affects the function StdioServerParameters of the component MCPSessionManager/MCPTool/MCPToolkit. The manipulation leads to os command injection. The attack may be initiated remotely. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

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

A command injection vulnerability exists in the StdioServerParameters function within the MCPSessionManager/MCPTool/MCPToolkit component of agentUniverse up to version 0.0.18. The function fails to properly sanitize input before passing it to OS-level command execution, allowing an attacker to inject arbitrary shell commands. The vulnerability is remotely exploitable and public exploits are available.

MitigationUpgrade agentUniverse to a version beyond 0.0.18 that patches the command injection in StdioServerParameters. If no patched version is available, implement strict input validation and use parameterized command execution methods instead of shell string interpolation.

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 agentUniverse is installed
    Locate the agentUniverse package in your environment using package managers (pip list, npm list, or similar), or search for agentUniverse directories in your project.
    Affected if agentUniverse is present in your environment
  2. Check the installed version of agentUniverse
    Run a version check command for agentUniverse (e.g., pip show agent universe, npm list agent-universe, or inspect the package version in your lock file).
    Affected if The installed version is 0.0.18 or any version prior to 0.0.18
  3. Verify if MCPToolkit or MCPTool component is in use
    Search your codebase for imports or references to MCPToolkit, MCPTool, or MCPSessionManager modules from agentUniverse.
    Affected if Your code imports or uses MCPToolkit, MCPTool, or MCPSessionManager components
  4. Check if StdioServerParameters function is invoked
    Search your codebase for any calls to StdioServerParameters function, particularly where external input may be passed as arguments.
    Affected if Your code calls StdioServerParameters function, especially with user-supplied or network-supplied input
  5. Inspect configuration for StdioServerParameters usage
    Review your application configuration files, environment variables, or runtime settings that may configure or invoke the StdioServerParameters function.
    Affected if StdioServerParameters is configured or enabled in your deployment

You are affected if agentUniverse version 0.0.18 or lower is installed and your environment uses the MCPToolkit/MCPTool component with the StdioServerParameters function exposed to external input.

From vendor data
Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Upgrade agentUniverse to a version beyond 0.0.18 that patches the command injection in StdioServerParameters. If no patched version is available, implement strict input validation and use parameterized command execution methods instead of shell string interpolation.
