CVE-2026-94037Public exploitNetwork attack vectorHinoki check available

Authenticated file disclosure via unchecked CSV path

Published Sep 20, 2026 · Updated Sep 20, 2026

Path traversal in 00Kisumi00 MCP File Analyzer allows remote authenticated users to read files accessible to the server process. The analyze_csv_data tool joins its filename argument to DATA_DIR without rejecting absolute paths or verifying that the resolved path remains inside the data directory, then passes the result to pandas.read_csv. Access to the MCP interface is required, and disclosure is limited to text files readable by the server process.
