What it is
From the CVE record
Cloud Foundry UAA Release, versions prior to 71.0, allows clients to be configured with an insecure redirect uri. Given a UAA client was configured with a wildcard in the redirect uri's subdomain, a remote malicious unauthenticated user can craft a phishing link to get a UAA access code from the victim.
