It also creates a RoleBinding to bind such Role to the entity operator ServiceAccount within the namespace where the Kafka cluster runs.\n\nAn attacker can craft a Kafka custom resource (in an attacker's namespace) with the `watchedNamespace` field set to a target namespace and then they can mint a token for the ServiceAccount (in the attacker's namespace)  to read/write Secrets in that target. This is valid with any target namespace for which the Cluster Operator has the rights (regardless the value of the  `STRIMZI_NAMESPACE` environment variable). The at-risk target namespaces are the namespaces which the user has given permissions to the Cluster Operator for, by creating related RoleBinding(s).\n\n### Patches\n\nThe issue is fixed in Strimzi 1.0.1 and 1.1.0 by adding a control to enable the watched namespac","public_affected_ranges":["<= 1.0.0"]}],"null_published_at":"2026-11-07T07:07:39.842Z","source_updated_at":"2026-06-18T13:04:44.000Z","source_disclosed_at":"2026-06-18T13:04:43.000Z","is_synthetic_fixture":false,"null_last_reviewed_at":null,"public_change_summary":"First indexed by Null; source disclosure date is shown separately.","null_first_observed_at":"2026-11-06T07:20:20.042Z"}],"next_cursor":null,"snapshot_revision":"42594"}
