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 detected in ef10007 MLOps_MCP 1.0.0. This impacts an unknown function of the file fastmcp_server.py of the component save_file Tool. The manipulation of the argument filename/destination results in path traversal. The attack may be performed from remote. The exploit is now public and may be used. The project was informed of the problem early through an issue report but has not responded yet.

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

Path traversal vulnerability in ef10007 MLOps_MCP 1.0.0's save_file tool within fastmcp_server.py allows remote attackers to manipulate the filename/destination arguments to write files outside the intended directory, potentially overwriting system files or accessing sensitive locations.

MitigationImplement strict input validation with path canonicalization to ensure the resolved path stays within an allowed directory whitelist; validate that the final normalized path does not escape the intended write 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. Check if MLOps_MCP package is installed
    Run 'pip show mlops_mcp' or 'pip list | grep -i mlops' to find if the ef10007 MLOps_MCP package is present in the Python environment
    Affected if The package is not installed - not affected; if installed, proceed to next checks
  2. Verify the installed version
    Run 'pip show mlops_mcp' and check the Version field, or import the package and check its __version__ attribute
    Affected if Version is exactly 1.0.0 - vulnerable; versions other than 1.0.0 may have different patch status
  3. Locate fastmcp_server.py in the installation
    Find the package installation path using 'python -c "import mlops_mcp; print(mlops_mcp.__file__)"' and navigate to locate fastmcp_server.py in that directory tree
    Affected if File exists at the expected location - vulnerable component is present
  4. Confirm save_file tool is exposed
    Examine fastmcp_server.py and search for function definitions related to 'save_file' or file upload/save operations that accept a filename or destination parameter
    Affected if A save_file tool/function accepting filename argument exists - the vulnerable code path is present
  5. Check for path traversal protection in the save_file function
    Review the save_file function code in fastmcp_server.py - inspect whether the filename parameter undergoes validation such as os.path.basename() stripping, allowlist checking, or secure base directory boundary enforcement before file write operations
    Affected if No input validation or path sanitization is performed on the filename parameter - the vulnerability is present and exploitable

If MLOps_MCP version 1.0.0 is installed, fastmcp_server.py exists, the save_file tool is exposed, and the filename parameter lacks validation/sanitization, the environment is affected by CVE-2026-7213.
