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.","epss":{"date":"2026-11-02","percentile":0.42058,"score":0.00489},"exploits":[],"kev":null,"metrics":[{"score":8.8,"severity":"high","source":"ADP: CISA-ADP","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"}],"modifiedAt":1793688588654,"publishedAt":1780299272229,"references":[{"source":"CNA: apache","tags":["patch"],"url":"https://github.com/apache/airflow/pull/60108"},{"source":"CNA: apache","tags":["vendor-advisory"],"url":"https://lists.apache.org/thread/wo09vrks8189dzsot39rvrx3vnx102tt"}],"remediation":[{"kind":"fix","source":"CNA: apache","text":"The reporting source identifies this reference as a patch.
