CVE-2026-55226
Strimzi: Unrestricted access to all Secrets within namespace watched by the Topic operator
Description
### Impact When only the Topic or only the User operators are deployed as part of the Entity Operator in the `Kafka` custom resource, the RBAC rights are not following the principle of least-privilege and the Entity Operator ServiceAccount still has access rights corresponding to both operators. That might allow the ServiceAccount to access `KafkaUser` custom resources and Secrets when the User operator is not deployed and access `KafkaTopic` custom resources when the Topic operator is not deployed. ### Patches The issue is fixed in Strimzi 1.0.1 and 1.1.0. ### Workarounds There is no workaround for this issue.
