The project confirms: "We've added an explicit non-empty check for wechatmp_token in verify_server() so that the /wx endpoint now fails closed with 403 Forbidden whenever the token is missing or left at the default empty value, instead of relying on a signature check that silently degenerates to a predictable hash."
