{"id":"GHSA-5j6p-jrrm-6x94","summary":"Apache Airflow: Execution API JWT leaked via KubernetesExecutor worker command-line args","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":["BIT-airflow-2026-49298","CVE-2026-49298","PYSEC-2026-2358"],"modified":"2026-07-13T16:43:49.991568470Z","published":"2026-06-01T09:31:15Z","database_specific":{"severity":"HIGH","github_reviewed":true,"github_reviewed_at":"2026-07-08T19:45:01Z","nvd_published_at":"2026-06-01T09:16:20Z","cwe_ids":["CWE-538"]},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-49298"},{"type":"WEB","url":"https://github.com/apache/airflow/pull/60108"},{"type":"WEB","url":"https://github.com/apache/airflow/pull"},{"type":"WEB","url":"https://lists.apache.org/thread/wo09vrks8189dzsot39rvrx3vnx102tt"}],"affected":[{"package":{"name":"apache-airflow-core","ecosystem":"PyPI","purl":"pkg:pypi/apache-airflow-core"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.2.2"}]}],"versions":["3.0.0","3.0.0rc1","3.0.0rc1.post1","3.0.0rc1.post2","3.0.0rc1.post3","3.0.0rc1.post4","3.0.0rc2","3.0.0rc3","3.0.0rc4","3.0.1","3.0.1rc1","3.0.2","3.0.2rc1","3.0.2rc2","3.0.3","3.0.3rc1","3.0.3rc2","3.0.3rc3","3.0.3rc4","3.0.3rc5","3.0.3rc6","3.0.4","3.0.4rc1","3.0.4rc2","3.0.5","3.0.5rc1","3.0.5rc2","3.0.5rc3","3.0.6","3.0.6rc1","3.0.6rc2","3.1.0","3.1.0b1","3.1.0b2","3.1.0rc1","3.1.0rc2","3.1.1","3.1.1rc1","3.1.1rc2","3.1.2","3.1.2rc1","3.1.2rc2","3.1.3","3.1.3rc1","3.1.4","3.1.4rc1","3.1.4rc2","3.1.5","3.1.5rc1","3.1.6","3.1.6rc1","3.1.7","3.1.7rc1","3.1.7rc2","3.1.8","3.1.8rc1","3.1.8rc2","3.2.0","3.2.0b1","3.2.0b2","3.2.0rc1","3.2.0rc2","3.2.1","3.2.1rc1","3.2.1rc2","3.2.1rc3","3.2.2rc1","3.2.2rc2","3.2.2rc3"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/06/GHSA-5j6p-jrrm-6x94/GHSA-5j6p-jrrm-6x94.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
