CVE-2026-86792

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 importstring, with no allowlist, and hand them to the confluent-kafka client which invokes them. Deployments that have enabled the Kafk...

CVE-2026-86792

The apache-airflow-providers-apache-kafka package (versions 1.15.0 before 2.0.0) is vulnerable to arbitrary code execution on the scheduler due to unsafe reflection. The root cause is the import_string function, which resolves dotted-path strings from a Kafka connection's extra field into Python ...

BIT-AIRFLOW-2026-58076 Apache Airflow: Unguarded import_string() of airflow_exc_ser / base_exc_ser exception nodes in BaseSerialization.deserialize enables DAG-author RCE on Scheduler / API Server

Apache Airflow's serialization layer reconstructed exception nodes by calling importstring on a class name taken from the serialized blob and instantiating it with arguments from the same blob, with no restriction on what could be imported. An operator's executorconfig reaches that branch, so a D...

BIT-AIRFLOW-2026-33264 Apache Airflow: DAG author RCE on webserver via unrestricted import_string() in BaseSerialization.deserialize()

A bug in BaseSerialization.deserialize allowed unrestricted importstring of attacker-controlled class paths when the Scheduler / API Server loaded a serialized DAG: a DAG author could embed a malicious trigger into a DAG to gain remote code execution on the API Server / Scheduler process, crossin...
