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.","public_affected_ranges":["< 3.2.2"]}],"null_published_at":"2026-11-05T19:10:21.468Z","source_updated_at":"2026-07-09T20:53:57.000Z","source_disclosed_at":"2026-06-01T09:31:13.000Z","is_synthetic_fixture":false,"null_last_reviewed_at":null,"public_change_summary":"First indexed by Null; source disclosure date is shown separately.","null_first_observed_at":"2026-11-04T23:34:40.400Z"}],"next_cursor":null,"snapshot_revision":"42594"}
