Deployments that have enabled the Kafka event producer \u2014 `dag_run_events_enabled` or `task_instance_events_enabled`, both disabled by default \u2014 build that client inside the scheduler process, so a user whose only privilege is editing Airflow connections gains arbitrary code execution in the control plane; the Airflow security model limits connection-configuration users to code execution on workers, not the scheduler. Deployments using Google Managed Kafka are not affected, because that code path overwrites any user-supplied `oauth_cb`; plain brokers and Amazon MSK are exposed. Users are recommended to upgrade to apache-airflow-providers-apache-kafka 2.0.0 or later, which adds an allowlist configuration option for connection-string callbacks."}], "lastModified": "2026-09-18T14:30:06.090", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:apache:apache-airflow-providers-apache-kafka:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "BE944DF3-BBD8-4B8A-A16C-1469DE0D0D7C", "versionEndExcluding": "2.0.0", "versionStartIncluding": "1.15.0"}], "operator": "OR"}]}], "sourceIdentifier": "security@apache.org"}
