CVE-2023-33234: Apache Airflow CNCF Kubernetes Provider: 
KubernetesPodOperator RCE via connection configuration
Severity: low

Affected versions:

- Apache Airflow CNCF Kubernetes Provider 5.0.0 through 6.1.0

Description:

Arbitrary code execution in Apache Airflow CNCF Kubernetes provider
version 5.0.0 allows user to change xcom sidecar image and
resources via Airflow connection.

In order to exploit this weakness, a user would already need
elevated permissions (Op or Admin) to change the connection
object in this manner.  Operators should upgrade to provider
version 7.0.0 which has removed the vulnerability.
