CVE-2026-94037: 00Kisumi00 mcp-file-analyzer analyze_csv_data MCP tool main.py ControlFlowNode path traversal
A weakness has been identified in 00Kisumi00 mcp-file-analyzer up to 84740852f0cf0cf5db4781b1ca6d7c6a6d210405. This affects the function ControlFlowNode of the file main.py of the component analyzecsvdata MCP tool. This manipulation of the argument filename causes path traversal. Remote exploitation of the attack is possible. The exploit has been made available to the public and could be used for attacks. This product follows a rolling release approach for continuous delivery, so version details for affected or updated releases are not provided. The project was informed of the problem early through an issue report but has not responded yet.

Frequently Asked Questions
What level of access does an attacker need?
The CVSS vector indicates low privileges are required. Exploitation is remote and has low attack complexity, but it is not described as unauthenticated.
How can teams determine whether their deployment is affected when no release versions are listed?
The affected code is identified as mcp-file-analyzer versions or revisions up to commit 84740852f0cf0cf5db4781b1ca6d7c6a6d210405. Because the project uses rolling releases, deployment status must be compared against the relevant source revision rather than a published version number.
Is there evidence that exploitation is practical?
Yes. A public exploit is available, and the CVSS exploit maturity rating is P, indicating proof-of-concept exploit code is available.
