{"cve":"CVE-2026-49298","nvd":{"published":"2026-06-01T09:16:20.770","modified":"2026-07-21T19:10:00.107","status":"Analyzed","description":"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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":8.8},"cwes":["CWE-538"],"references":["https://github.com/apache/airflow/pull/60108","https://lists.apache.org/thread/wo09vrks8189dzsot39rvrx3vnx102tt"],"products":["apache:airflow"],"source":"nvd","synced_at":"2026-10-19T22:37:48.043517290+00:00"},"epss":{"cve":"CVE-2026-49298","score":0.00489,"percentile":0.4208,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-5j6p-jrrm-6x94","url":"https://osv.dev/vulnerability/GHSA-5j6p-jrrm-6x94","summary":"Apache Airflow: Execution API JWT leaked via KubernetesExecutor worker command-line args","modified":"2026-07-13T16:43:49.991568470Z","packages":[{"ecosystem":"PyPI","name":"apache-airflow-core","purl":"pkg:pypi/apache-airflow-core","ranges":["<3.2.2"],"fixed":["3.2.2"]}]},{"id":"PYSEC-2026-2358","url":"https://osv.dev/vulnerability/PYSEC-2026-2358","summary":"Apache Airflow: Execution API JWT leaked via KubernetesExecutor worker command-line args","modified":"2026-07-13T16:43:49.991568470Z","packages":[{"ecosystem":"PyPI","name":"apache-airflow-core","purl":"pkg:pypi/apache-airflow-core","ranges":["<3.2.2"],"fixed":["3.2.2"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
