Miggo AIRoot Cause Analysis

The vulnerability explicitly affects federation and shovel endpoints that process vhost/node name parameters. These ERlang functions are core to handling management UI rendering for their respective plugins. The XSS vulnerability stems from: 1) Admin-controlled parameters being reflected in HTML responses 2) Lack of output encoding context (vhosts/node names used in HTML without escaping) 3) The functions' role in endpoint handling as part of RabbitMQ's management plugin architecture. While exact line numbers aren't available, the combination of endpoint responsibility and parameter handling makes these functions clear candidates.
