GHSA-mj6p-p843-x5wc Observability Operator is vulnerable to Incorrect Privilege Assignment through its Custom Resource MonitorStack

• Go github.com/rhobs/observability-operator: < 1.3.0 → fixed in 1.3.0

A flaw was found in the Observability Operator. The Operator creates a ServiceAccount with *ClusterRole* upon deployment of the *Namespace-Scoped* Custom Resource MonitorStack. This issue allows an adversarial Kubernetes Account with only namespaced-level roles, for example, a tenant controlling a namespace, to create a MonitorStack in the authorized namespace and then elevate permission to the cluster level by impersonating the ServiceAccount created by the Operator, resulting in privilege escalation and other issues.
