CVE-2024-29735Network attack vector

SSH disruption via recursive parent permission changes

Published Mar 26, 2024 · Updated Feb 13, 2025

Improper permission handling in Apache Airflow 2.8.2 through 2.8.3 allows remote authenticated users to make parent directories group-writable. FileTaskHandler._prepare_log_folder invokes _change_directory_permissions_up, which recursively applies the configured 0o775 mode to every owned parent directory. Exposure requires a local or virtualenv installation or a non-isolated third-party container; with umask 022 and logs under a home directory, SSH login can fail after the home directory becomes group-writable.
