Technical details

The vulnerability is an improper input validation issue (CWE-74) in the KubernetesPodOperator's handling of connection configuration. Versions 5.0.0 through 6.2.0 allow authenticated users with elevated privileges (Operator or Admin role) to modify the xcom sidecar image and resource specifications through the Airflow connection object. No user interaction or additional preconditions are required beyond the initial privilege level. An attacker can exploit this to execute arbitrary code within Kubernetes pods. The vulnerability was fixed in version 7.0.0 by removing the vulnerable configuration mechanism.

Affected products
