CVE-2026-27173 Details
Description
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.
A vulnerability exists in the Apache Airflow CNCF Kubernetes provider, specifically in versions prior to 10.17.0. JWT tokens used by workers in Kubernetes Executors have been exposed to users with read-only access to Kubernetes Pods. This exposure could enable these users to perform actions available to running tasks via the Task SDK, potentially allowing them to modify the state of the Airflow Database for those tasks.
Users can update to Apache Airflow CNCF Kubernetes provider version 10.17.0 or later to address this vulnerability.
