Description
Authentication Bypass in cf-auth-proxy in Cloud Foundry Foundation all installations allows an unauthenticated remote attacker to gain read access to every log and metric for every application and platform component via minting a JWT that the cf-auth-proxy accepts as a valid logs.admin token.
