{"id":"BIT-airflow-2026-49298","summary":"Apache Airflow: JWT Token Exposure in KubernetesExecutor Command-Line Arguments","details":"A bug in Apache Airflow's KubernetesExecutor caused JWT tokens used by worker pods to authenticate against the Execution API to be passed to the worker container as command-line arguments visible in the pod spec. An authenticated UI/API user with Kubernetes read-only access to the cluster (e.g. `pods/get` in the Airflow namespace) could harvest the JWT from `kubectl describe pod` output and then call state-mutating Execution API endpoints — triggering Dag runs, clearing runs, reading or writing Variables / Connections / XComs — as if they were a running task. Affects deployments using the `KubernetesExecutor`. Users are advised to upgrade to `apache-airflow` 3.2.2 or later. This is the airflow-core half of the same vulnerability addressed by [CVE-2026-27173](https://www.cve.org/CVERecord?id=CVE-2026-27173), which shipped the apache-airflow-providers-cncf-kubernetes side of the fix. Deployments that already upgraded `apache-airflow-providers-cncf-kubernetes` to 10.17.0 or later per the CVE-2026-27173 advisory should additionally upgrade `apache-airflow` to 3.2.2 or later to close the core-side surface — the two fixes are complementary, not duplicates.","aliases":["CVE-2026-49298","GHSA-5j6p-jrrm-6x94","PYSEC-2026-2358"],"modified":"2026-09-08T08:45:27.834814420Z","published":"2026-06-05T05:40:52.457Z","database_specific":{"severity":"High","cpes":["cpe:2.3:a:apache:airflow:*:*:*:*:*:python:*:*"]},"references":[{"type":"FIX","url":"https://github.com/apache/airflow/pull/60108"},{"type":"ADVISORY","url":"https://lists.apache.org/thread/wo09vrks8189dzsot39rvrx3vnx102tt"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-49298"}],"affected":[{"package":{"name":"airflow","ecosystem":"Bitnami","purl":"pkg:bitnami/airflow"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"3.2.2"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/airflow/BIT-airflow-2026-49298.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}],"schema_version":"1.9.0"}
