How to Fix CVE-2026-7149

To remediate this vulnerability, upgrade all affected Kaggle mcp dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

kaggle-mcp fixed: Latest secure release 
pip install kaggle-mcp>=Latest secure release
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

pip show kaggle-mcp

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2026-7149, inspect your installed packages using pip:

pip show kaggle-mcp

Analyze the terminal output to locate any version of Kaggle mcp in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than the patched release), your application is affected.

Note: The pip show kaggle-mcp command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal'), where the product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. In Kaggle mcp, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

A vulnerability has been found in dexhunter kaggle-mcp up to 406127ffcb2b91b8c10e20e6c2ca787fbc1dc92d. This vulnerability affects the function prepare_kaggle_dataset of the file src/kaggle_mcp/server.py. The manipulation of the argument competition_id leads to path traversal. The attack is possible to be carried out remotely. The exploit has been disclosed to the public and may be used. This product adopts a rolling release strategy to maintain continuous delivery. Therefore, version details for affected or updated releases cannot be specified. The project was informed of the problem early through an issue report but has not responded yet.
