CVE-2018-1256

Estado: ModificadaAlta (8.1)—

Spring Cloud SSO Connector, version 2.1.2, contains a regression which disables issuer validation in resource servers that are not bound to the SSO service. In PCF deployments with multiple SSO service plans, a remote attacker can authenticate to unbound resource servers which use this version of the SSO Connector with tokens generated from another service plan.
