CVE-2026-68982
Published:November 09, 2026
Updated:November 09, 2026
Apache Airflow's CeleryExecutor ran callback workloads ("ExecuteCallback", used for deadline-alert callbacks) without validating the workload's authentication token. Anyone able to write to the Celery broker could enqueue a forged callback and execute arbitrary code on every CeleryExecutor worker, without Airflow credentials. Deployments using the CeleryExecutor are affected.
Users are advised to upgrade to apache-airflow 3.4.0 or later, in which the worker claims the callback through the Execution API, validating the token, before running it.
