Aiven Operator
Monthly
Aiven Operator versions 0.31.0 through 0.36.x allow developers with ClickhouseUser CRD creation permissions in their own namespace to exfiltrate secrets from arbitrary namespaces by exploiting a confused deputy vulnerability in the operator's ClusterRole. An attacker can craft a malicious ClickhouseUser resource that causes the operator to read privileged credentials (database passwords, API keys, service tokens) from production namespaces and write them into the attacker's namespace with a single kubectl apply command. The vulnerability is fixed in version 0.37.0.
