CVE-2019-9837: URL Redirection to Untrusted Site (Open Redirect)

March 21, 2019 (updated March 27, 2019)

Doorkeeper::OpenidConnect (aka the OpenID Connect extension for Doorkeeper) 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.
