Miggo AIRoot Cause Analysis

The vulnerability stems from improper handling of URL schemes in webhook payloads. The advisory explicitly states that pre-3.6.11 versions lacked URL scheme restrictions, and the fix added sanitization. Webhook processing functions would be the primary location where raw URLs are accepted and processed. The high confidence comes from: 1) The vulnerability pattern matches unvalidated URL handling in webhook endpoints 2) The CWE-79 classification directly implies input neutralization failures during web page generation 3) The patch's stated purpose (URL sanitization) indicates the vulnerable functions were involved in processing/storing webhook URLs.
