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
PraisonAI is a multi-agent teams system. Prior to version 4.6.9, the fix for PraisonAI's MCP command handling does not add a command allowlist or argument validation to parse_mcp_command(), allowing arbitrary executables like bash, python, or /bin/sh with inline code execution flags to pass through to subprocess execution. This issue has been patched in version 4.6.9.

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

Command injection vulnerability in PraisonAI's MCP command handling where parse_mcp_command() lacks command allowlist or argument validation, allowing arbitrary executables (bash, python, /bin/sh) with inline code execution flags to pass through to subprocess execution.

MitigationUpgrade to version 4.6.9 or later which implements command allowlisting and argument validation in parse_mcp_command(). If upgrading is not immediately possible, disable or restrict MCP command functionality as a temporary mitigation.

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 installed PraisonAI version
    Run 'pip show praisonai' or check the package version in your environment (e.g., pip list | grep -i praison)
    Affected if Version is lower than 4.6.9
  2. Locate parse_mcp_command function
    Search the codebase for the parse_mcp_command function in the installed package files (e.g., grep -r 'parse_mcp_command' in site-packages)
    Affected if Function exists and lacks command allowlisting or argument validation logic
  3. Verify MCP command execution path
    Inspect how parse_mcp_command handles input before subprocess execution - look for subprocess.Popen or similar calls receiving unsanitized user input
    Affected if Raw command arguments are passed directly to subprocess without validation or allowlist checks
  4. Check for command allowlist implementation
    Review parse_mcp_command source code for an allowed_commands list or similar allowlisting mechanism
    Affected if No allowlist exists and any executable name can be passed as a command
  5. Assess MCP feature exposure
    Determine if MCP command handling is accessible in your deployment (check configuration files, API endpoints, or user-accessible interfaces)
    Affected if MCP commands can be invoked by users or external inputs without restrictions

You are affected if running Praison Praisonai version lower than 4.6.9 and the parse_mcp_command function can be invoked with user-controlled input without validation.

Interim mitigation

Upgrade to version 4.6.9 or later which implements command allowlisting and argument validation in parse_mcp_command(). If upgrading is not immediately possible, disable or restrict MCP command functionality as a temporary mitigation.

Recommended fix High confidence

4.6.9

  1. Check the current installed version of PraisonAI (e.g., pip show praisonai or pip list)
  2. Upgrade PraisonAI to version 4.6.9 or later using: pip install --upgrade praisonai
  3. Verify the upgrade was successful by checking the installed version: pip show praisonai
  4. Test that the MCP command handling functions correctly after the upgrade
