Stackrox: stackrox: saml response replay allows multiple central authentication tokens
A flaw was found in Red Hat Advanced Cluster Security for Kubernetes (RHACS).

An attacker who obtains a valid, unexpired signed SAML response can submit it multiple times and receive distinct Central authentication tokens for the mapped identity.
