Summary
In Apache Airflow prior to 2.3.4, an insecure umask was configured for numerous Airflow components when running with the `--daemon` flag which could result in a race condition giving world-writable files in the Airflow home directory and allowing local users to expose arbitrary file contents via the webserver.
Patch / fix
- pypi apache-airflow 2.3.4
- bitnami airflow 2.3.4
- apache airflow 2.3.4
Exploit prediction
0.62% chance of exploitation in the next 30 days, higher than 49% of all scored CVEs (FIRST EPSS, 2026-11-08).
