Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

Code Execution: User-supplied or LLM-generated filenames interpolated directly into executable Python code templates without proper escaping allowed arbitrary code execution. Avoid using string formatting on dynamically sourced filenames in code templates; use repr() or safe parameterization instead.

Remote Code Execution: Parsing untrusted YAML configurations with safe_load_all was vulnerable to code execution when payloads contained blocked keys such as 'args'. Strict schema and field denylisting is required on any dynamic configuration parser.

Path Traversal: File-handling APIs and YAML builders allowed traversal across directory boundaries via raw path concatenation. Implement strict canonicalization and prefix verification to confine file operations to a designated root directory.
