CVE-2026-48892
Published:July 07, 2026
Updated:August 04, 2026
The Config API in Apache Airflow surfaced per-key secrets-backend overrides (environment variables like "AIRFLOW__SECRETS__BACKEND_KWARG__SECRET_ID" and "AIRFLOW__WORKERS__SECRETS_BACKEND_KWARG__SECRET_ID") as synthetic config options whose option names were not in "sensitive_config_values", so the masker did not redact them. An authenticated UI/API user with Config read permission could retrieve plaintext secrets-backend credentials (Vault "role_id" / "secret_id", etc.) from the Config API output. Affects deployments that configure secrets backends via per-key environment overrides. Users are advised to upgrade to "apache-airflow" 3.3.0 or later.
