Description

Arbitrary code execution in Apache Airflow CNCF Kubernetes provider version 5.0.0 allows user to change xcom sidecar image and resources via Airflow connection.

In order to exploit this weakness, a user would already need elevated permissions (Op or Admin) to change the connection object in this manner.  Operators should upgrade to provider version 7.0.0 which has removed the vulnerability.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for apache-airflow-providers-cncf-kubernetes, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update apache-airflow-providers-cncf-kubernetes to 7.0.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2023-33234 is resolved across your whole dependency graph.

  3. Workarounds

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
