What is CVE-2026-49298?

A flaw in the KubernetesExecutor of Apache Airflow allows JWT tokens used for authenticating worker pods against the Execution API to be visible in command-line arguments within the pod spec. Users with read-only access in Kubernetes can exploit this issue to retrieve these tokens from 'kubectl describe pod' output. By obtaining these tokens, an attacker can invoke state-modifying operations via the Execution API, such as triggering DAG runs and manipulating Variables or Connections. Users are recommended to upgrade to Apache Airflow version 3.2.2 or newer to mitigate this vulnerability, which complements earlier fixes provided in related advisories.

Affected Version(s)

Apache Airflow 0 < 3.2.2
