The vulnerability stems from the removed 'CheckOrigin: func(r *http.Request) bool { return true }' line in websocket.Upgrader configuration. This custom implementation disabled security checks by automatically approving all origin headers. The patch removed this override, restoring the library's default origin validation. The combination of CWE-352 (CSRF) and CWE-863 (Incorrect Authorization) aligns with this finding, as improper origin validation allows unauthorized WebSocket connections.
