The docker_pull module uses the realm parameter from a Docker registry's WWW-Authenticate response header as the authentication endpoint without validation. An attacker in a man-in-the-middle position between bbot and a Docker registry could modify this header to redirect the authentication request to an arbitrary endpoint, potentially leaking authentication tokens.
