Description
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 analyze_csv_data 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.
