SCA: security update for apache-airflow (GHSA-89cj-xrpx-j79m)

medium Tenable Self-Hosted Container Security Plugin ID 444732

Description

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

 - A Dag author could either (a) create a symlink under their task's log directory pointing to an arbitrary
 file readable by the API server process (read-path attack — e.g. `/etc/passwd` or `airflow.cfg`) or (b)
 supply a `task_id` containing `..` sequences accepted by the Task SDK's `KEY_REGEX` (write-path attack),
 and in both cases the FileTaskHandler resolves the log path outside the configured `base_log_folder`,
 leaking or overwriting arbitrary files. Only affects deployments where the worker log folder is shared
 with the API server. Users are advised to upgrade to `apache-airflow` 3.2.2 or later. As a defense-in-
 depth mitigation, deploy the worker and API server with separate log volumes so that worker-controlled
 paths cannot reach the API server's filesystem. (CVE-2026-40861)

Solution

Update the apache-airflow library and its related packages to version 3.2.2 or later.
