CVE-2023-33234 — Apache Apache-Airflow-Providers-Cncf-Kubernetes security vulnerability

High CVSS 7.2

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.

Matched remediation archetype

Command, code, expression, and template injection

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Trace untrusted values to process execution, interpreters, evaluators, template engines, dynamic imports, and administrative scripting features.
  • Determine whether the affected path is reachable across each trust boundary and which service account or host privilege it inherits.
  • Review configuration for optional execution features, unsafe compatibility modes, and shell invocation.

Remediate safely

  • Replace string-built commands or evaluated code with fixed operations and structured argument APIs that do not invoke a shell.
  • Use strict allowlists for operation identifiers and reject unexpected input before it reaches any interpreter.
  • Update the affected component and add inert regression tests covering metacharacters, encoding variants, and alternate request paths.
