Miggo AIRoot Cause Analysis

The critical vulnerability stemmed from two key functions: 1) retrieve_location_from_cookie_or_service directly used YAML.load on user-controlled cookie data (CWE-502), which allows deserialization of arbitrary objects and code execution. This was patched by replacing YAML with JSON in the commit. 2) store_ip_location's use of to_yaml created the persistent attack vector in cookies. The high confidence comes from the explicit YAML.load usage in the retrieval path being called out in vulnerability reports and the patch directly addressing both serialization/deserialization methods.
