SCA: security update for apache-airflow (GHSA-8prw-8m6x-8w6f)

high Tenable Self-Hosted Container Security Plugin ID 472208

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Apache Airflow's serialization layer reconstructed exception nodes by calling `import_string()` on a class
 name taken from the serialized blob and instantiating it with arguments from the same blob, with no
 restriction on what could be imported. An operator's `executor_config` reaches that branch, so a Dag
 author could place a value there that causes an arbitrary callable to be imported and invoked -- for
 example `subprocess.check_output`, or `builtins.eval` on the `builtins`-prefixed variant. The code runs in
 the **Scheduler**, which reconstructs serialized Dags in its normal loop with no request involved, and in
 the **API server**, on any authenticated read of the Dag such as `GET /api/v2/dags/{dag_id}/details`. Both
 are components the Airflow security model states must never execute Dag-author code, and both hold the
 metadata database credentials and the JWT signing secret. No non-default configuration is required. This
 is a **different sink from CVE-2026-33264**, which covered only the trigger branch of the same
 deserializer: deployments that upgraded in response to that advisory are still affected through the
 exception branch and must upgrade again. Users are advised to upgrade to apache-airflow 3.3.1 or later,
 which restricts the imported class to a subclass of `BaseException`. (CVE-2026-58076)

Solution

Update the apache-airflow library and its related packages to version 3.3.1 or later.
