pa_agent

The system includes a `save_uploaded_file` tool that allows writing arbitrary base64-encoded content to any specified filename, making it highly vulnerable to arbitrary file write attacks, which can lead to remote code execution or system compromise if not sandboxed. It also executes external `npx` commands for the CoinMarketCap MCP server, which, while for a specific tool, introduces a potential command injection vector if not meticulously sanitized. Several tools (`web_fetch`, `index_docs`, `summarise_file`, `extract_tables`, `ocr_image`) download and process content from user-provided URLs, posing risks like SSRF, DoS via large files, and exploitation of vulnerabilities in parsing libraries. There is no clear indication of sandboxing or resource limiting for these operations.
