GHSA-89cj-xrpx-j79m: Apache Airflow has a Link Following issue

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.
