CVE-2026-48892

Full vulnerability record from the local CVENow database.

Description

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.

Un usuario autenticado de UI/API con permiso de lectura de Config podía recuperar credenciales de backend de secretos en texto plano (Vault “role_id” / “secret_id”, etc.) de la salida de la API de Config. Afecta a las implementaciones que configuran backends de secretos a través de anulaciones de entorno por clave. Se aconseja a los usuarios actualizar a “apache-airflow” 3.3.0 o posterior."
