title: Doorkeeper::OpenidConnect Open Redirect
description: Doorkeeper::OpenidConnect (aka the OpenID Connect extension for Doorkeeper)
  1.4.x and 1.5.x before 1.5.4 has an open redirect via the redirect_uri field in
  an OAuth authorization request (that results in an error response) with the 'openid'
  scope and a prompt=none value. This allows phishing attacks against the authorization
  flow.
