|---|
| Description | An Arbitrary File Read and Write vulnerability was discovered in excel-mcp 1.0.2. The vulnerability exists in multiple MCP tools (including read_file and write_file) within src/index.ts and related handlers. The application accepts caller-controlled file path arguments (e.g., filePath, outputPath) and passes them directly to local filesystem APIs without enforcing a workspace root or sandbox directory. A remote authenticated attacker can exploit this to read sensitive spreadsheet files or write/overwrite arbitrary CSV/XLSX files in any directory writable by the server process, potentially leading to information disclosure or system compromise. |
