Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Apache Airflow's apache-airflow-providers-apache-kafka versions 1.15.0 before 2.0.0 resolve dotted-path strings from a Kafka connection's extra field into Python callables without an allowlist and pass them to the confluent-kafka client. A user who can only edit Airflow connections can gain arbitrary code execution in the scheduler when the Kafka event producer is enabled, which is off by default. Upgrade to apache-airflow-providers-apache-kafka 2.0.0 or later, which adds an allowlist option for these callbacks.
