{"schema_version": "1.6.1", "id": "CVE-2026-86792", "summary": "Connection-editor remote code execution on the Scheduler via Kafka connection callback configuration", "details": "Apache Airflow Apache Kafka provider versions 1.15.0 before 2.0.0 resolve dotted-path strings found in a Kafka connection's `extra` field into Python callables via `import_string`, with no allowlist, and hand them to the confluent-kafka client which invokes them. Deployments that have enabled the Kafka event producer — `dag_run_events_enabled` or `task_instance_events_enabled`, both disabled by default — 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.", "affected": [{"ranges": [{"type": "SEMVER", "events": [{"introduced": "1.15.0"}, {"fixed": "2.0.0"}]}]}], "references": [{"type": "WEB", "url": "https://github.com/apache/airflow/pull/72208"}, {"type": "WEB", "url": "https://lists.apache.org/thread/jl4gpok02313yh3rvtvj8qbo11c6zpr2?users@airflow.apache.org"}, {"type": "WEB", "url": "https://lists.apache.org/thread/jl4gpok02313yh3rvtvj8qbo11c6zpr2"}]}
