Miggo AIRoot Cause Analysis

The vulnerability stemmed from two key functions: 1) verified_request? relied on forgery_whitelisted? which improperly allowed XHR/non-HTML requests without CSRF tokens. 2) forgery_whitelisted? itself contained the flawed logic that permitted these unsafe validations. The patch removed XHR/content type checks and restricted whitelisting to GET requests, confirming these were the vulnerable components. The commit diff and CVE description directly correlate to these function changes.
