Miggo AIRoot Cause Analysis

The vulnerability stemmed from case-sensitive handling of disallowed field patterns. The pre-patch setDisallowedFields() method stored patterns in canonical form without case normalization, while isAllowed() performed case-sensitive matching. This required developers to list both uppercase and lowercase variants of field names for effective protection. The commit shows these functions were modified to add lowercase conversion (setDisallowedFields) and case-insensitive matching (isAllowed), confirming their role in the vulnerability.
