CAS_NLP_Module3_Calibre_Project

Extensive use of `subprocess.run` to interact with `calibredb` and `ebook-meta` CLI tools. Several tool parameters (e.g., `search_term`, `query`, `file_path`, `title`, `authors`, `isbn` in `calibre_tools/cli_wrapper.py`) are passed directly from user input without explicit sanitization, posing a risk of command injection, which could lead to arbitrary code execution or data manipulation if the underlying Calibre CLI tools are vulnerable to such input. The `calibre_sql` tool executes arbitrary SQL queries (though in read-only mode), which could lead to information disclosure of database schema or denial-of-service via resource-intensive queries. No obvious hardcoded secrets were found. Consider implementing `shlex.quote` for all user-provided arguments passed to subprocess calls.
