Miggo AIRoot Cause Analysis

The vulnerability stemmed from improper input sanitization sequence in the Balance model's validation logic. The test() method originally validated the codbalance field with a regex check before applying HTML escaping, creating an XSS vector through validation error messages. The patch fixed this by moving the noHtml() sanitization to occur before validation. The unit tests added in the commit specifically verify HTML escaping behavior, confirming the pre-patch vulnerability in field handling.
