{"id":"BIT-airflow-2026-48892","summary":"Apache Airflow: Config API leaks per-key secrets backend kwargs - masker bypass on synthetic options","details":"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.","aliases":["CVE-2026-48892","GHSA-9933-5rrp-mfwx","PYSEC-2026-2087"],"modified":"2026-09-08T08:45:27.620503580Z","published":"2026-07-12T23:39:19.972Z","database_specific":{"severity":"Medium","cpes":["cpe:2.3:a:apache:airflow:*:*:*:*:*:*:*:*"]},"references":[{"type":"ADVISORY","url":"http://www.openwall.com/lists/oss-security/2026/07/07/4"},{"type":"REPORT","url":"https://github.com/apache/airflow/pull/67622"},{"type":"ADVISORY","url":"https://lists.apache.org/thread/pq5yy40079h6tzh3fxvw28dd8dbk72hk"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-48892"}],"affected":[{"package":{"name":"airflow","ecosystem":"Bitnami","purl":"pkg:bitnami/airflow"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"3.3.0"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/airflow/BIT-airflow-2026-48892.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N"}]}],"schema_version":"1.9.0"}
