A vulnerability was found in the search-api container in Red Hat Advanced Cluster Management for Kubernetes when a query in the search filter gets parsed by the backend. This flaw allows an attacker to craft specific strings containing special characters that lead to crashing the pod and affects system availability while restarting.

The golang.org/x/crypto/ssh package before 0.0.0-20220314234659-1baeb1ce4c0b for Go allows an attacker to crash a server in certain circumstances involving AddHostKey.

A flaw was found in rhacm versions before 2.0.5 and before 2.1.0. Two internal service APIs were incorrectly provisioned using a test certificate from the source repository. This would result in all installations using the same certificates. If an attacker could observe network traffic internal to a cluster, they could use the private key to decode API requests that should be protected by TLS sessions, potentially obtaining information they would not otherwise be able to. These certificates are not used for service authentication, so no opportunity for impersonation or active MITM attacks were made possible.

An issue was discovered in ManagedClusterView API, that could allow secrets to be disclosed to users without the correct permissions. Views created for an admin user would be made available for a short time to users with only view permission. In this short time window the user with view permission could read cluster secrets that should only be disclosed to admin users.
