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 flaw has been found in elinsky execution-system-mcp 0.1.0. The impacted element is the function _get_context_file_path of the file src/execution_system_mcp/server.py of the component add_action Tool. This manipulation of the argument context causes path traversal. The attack can be initiated remotely. The exploit has been published and may be used.

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 path traversal vulnerability exists in the _get_context_file_path function within src/execution_system_mcp/server.py of the execution-system-mcp package version 0.1.0. The add_action Tool fails to properly sanitize the 'context' argument, allowing attackers to manipulate file paths using directory traversal sequences (e.g., ../../../) to access files outside the intended directory.

MitigationImplement strict input validation and canonicalization of the context path argument in _get_context_file_path, ensuring the resolved path stays within the intended base directory. Use os.path.realpath() to resolve symlinks and verify the path prefix matches the allowed directory.

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 execution-system-mcp is installed
    Run 'pip show execution-system-mcp' or check your Python environment for the package
    Affected if The package is not installed or version is not 0.1.0 (no other versions listed as affected)
  2. Locate the vulnerable server.py file
    Find src/execution_system_mcp/server.py in your installation directory or package path
    Affected if The file exists in version 0.1.0 of the package
  3. Verify the _get_context_file_path function exists
    Open server.py and search for the _get_context_file_path function definition
    Affected if The function is present without proper path validation on the 'context' parameter
  4. Confirm add_action Tool is in use
    Check your application configuration or code that imports and uses the add_action Tool from this package
    Affected if The add_action Tool is being used and accepts a 'context' argument
  5. Test for path traversal susceptibility
    If the add_action Tool accepts user input for the 'context' parameter, inspect whether the code validates or sanitizes directory traversal sequences like ../
    Affected if The 'context' argument accepts unsanitized user input containing ../ sequences

You are affected if you have execution-system-mcp version 0.1.0 installed and use the add_action Tool with a 'context' parameter that accepts unvalidated user input, allowing directory traversal attacks.

Mitigation

Implement strict input validation and canonicalization of the context path argument in _get_context_file_path, ensuring the resolved path stays within the intended base directory. Use os.path.realpath() to resolve symlinks and verify the path prefix matches the allowed directory.
