Description

Apache Airflow: Config API leaks per-key secrets backend kwargs - masker bypass on synthetic options

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.

How this vulnerability can be exploited

This issue can be reached over the network, attack complexity is low, an attacker needs low-level privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality high, integrity none, availability none.
