SCA: security update for apache-airflow (GHSA-2qjv-p2gc-mjg2)

high Tenable Self-Hosted Container Security Plugin ID 472164

Description

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

 - Apache Airflow's Task SDK rebuilt a `Callback` object from serialized data by re-running its constructor,
 which imports the module named by the stored callback path. Because `SyncCallback` is itself an Airflow
 class it passes the default `allowed_deserialization_classes` allow-list, so tightening that setting does
 not help. A Dag author — who controls a task instance's `next_kwargs` through the task execution API — can
 therefore cause an arbitrary module to be imported inside the scheduler process, when the scheduler's
 `awaiting_input` timeout sweep deserializes that value. No non-default configuration is required; the
 sweep runs unconditionally. Versions before 3.3.0 are not affected: the class existed, but the scheduler
 sweep that reaches it did not. This is a separate code path from CVE-2026-58076 and CVE-2026-67260, which
 cover different gadgets reaching deserialization — applying either of those fixes does not address this
 one. Users are advised to upgrade to apache-airflow 3.3.1 or later. (CVE-2026-67587)

Solution

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