CVE-2026-49298 · Severity: high · CVSS 8.8 · Published 2026-06-01

A security flaw in Apache Airflow's KubernetesExecutor causes sensitive authentication tokens (JWTs) to be exposed in plain text within Kubernetes pod configurations. An attacker with basic read-only access to the Kubernetes cluster could steal these tokens to impersonate a running task. This would allow them to unauthorizedly trigger or clear workflows, and read or modify sensitive business data such as Variables, Connections, and XComs.

**How severe is CVE-2026-49298?** High severity, with a CVSS score of 8.8, published 1 June 2026.

**Which products and versions are affected?** Apache Airflow < 3.2.2; apache-airflow-core (PyPI) < 3.2.2, ECOSYSTEM:introduced=0,fixed=3.2.2.

**Is there a fix for CVE-2026-49298?** Yes. apache-airflow-core (PyPI): upgrade to 3.2.2 or later. Junglewise finds every place you run it, drafts the upgrade and applies it once you approve.

**How is CVE-2026-49298 attacked?** It is attacked over the network, in a software library.

**Am I affected by CVE-2026-49298?** Check whether you run Apache Airflow or apache-airflow-core (PyPI) at an affected version. Junglewise does that check for you around the clock: connect your code, cloud and domains, and it matches new vulnerabilities like this one against what you actually run and tells you when one reaches you.

## How to fix

- apache-airflow-core (PyPI): upgrade to 3.2.2 or later

  ```sh
  pip install "apache-airflow-core>=3.2.2"
  ```


## Technical details

A vulnerability in Apache Airflow's KubernetesExecutor (CWE-538) causes JWT tokens used for Execution API authentication to be passed as command-line arguments to worker containers. These arguments are visible in the Kubernetes pod specification, making them accessible to any user with 'pods/get' permissions in the Airflow namespace. An attacker can harvest these tokens to call state-mutating Execution API endpoints, enabling them to trigger DAG runs, clear runs, or manipulate Variables, Connections, and XComs. This issue is the core-side component of a coordinated fix (alongside CVE-2026-27173). Users should upgrade to apache-airflow 3.2.2 or later.
