Miggo AIRoot Cause Analysis

The vulnerability stems from the get_doc_md method's template rendering logic shown in the commit diff. The original code (before patching) used jinja2.Template() and env.get_template() to process doc_md, enabling code execution via template injection. The patch removed all Jinja rendering, confirming this was the attack vector. The function's role in processing user-controlled doc_md parameters matches the CWE-94 (Code Injection) description in the advisory.
