CVE-2026-27173: Apache Apache-Airflow-Providers-Cncf-Kubernetes

High severity, CVSS 8.7. EPSS: 0.2% chance of exploitation in the next 30 days.

JWT tokens that were used by workers in Kubernetes Executors have been exposed to users who had read only access to Kuberentes Pods. This could allow users with just read-only access to perform actions that were only available to running tasks via Task SDK and potentially allow to modify state of Airflow Database for tasks.

Affected products

• Apache Apache-Airflow-Providers-Cncf-Kubernetes: before 10.17.0 (fixed in 10.17.0)
