VCID-kkj7-z9k5-5qe2	Doorkeeper application secret information disclosure vulnerability Information disclosure vulnerability. Allows an attacker to see all Doorkeeper::Application model attribute values (including secrets) after authorizing an application to their user. An application is vulnerable if the authorized applications controller is enabled (GET /oauth/authorized_applications.json). Recommended additional hardening for >= 5.1 is to enable application secrets hashing. This would render the exposed secret useless.	CVE-2020-10187 GHSA-j7vx-8mqj-cqp9
