{"id":"CVE-2026-48892","published":"2026-07-07T09:16:26Z","modified":"2026-09-16T14:55:24Z","title":"Apache Airflow: Config API leaks per-key secrets backend kwargs - masker bypass on synthetic options","vendor":"Apache","product":"Apache Airflow","tier":"tail","description":{"text":"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.","provenance":"source","from":"CVE.org"},"cvss":{"score":6.5,"severity":"MEDIUM","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","provenance":"source","from":"CISA ADP Vulnrichment"},"epss":{"score":0.00664,"percentile":0.51598,"provenance":"source"},"cwes":[{"id":"CWE-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"}],"references":[{"url":"https://github.com/apache/airflow/pull/67622","tags":["patch"]},{"url":"https://lists.apache.org/thread/pq5yy40079h6tzh3fxvw28dd8dbk72hk","tags":["vendor-advisory"]},{"url":"http://www.openwall.com/lists/oss-security/2026/07/07/4","tags":[]}],"priority":{"score":14.9,"factors":[{"name":"EPSS percentile","points":10.32},{"name":"CVSS severity","points":4.55}]},"vendorSlug":"apache","affectedVersions":[{"vendor":"Apache Software Foundation","product":"Apache Airflow","versions":["< 3.3.0"]}],"affected":[{"ecosystem":"PyPI","package":"apache-airflow","vulnerableRanges":["<3.3.0"],"patched":["3.3.0"],"from":["GHSA-9933-5rrp-mfwx","PYSEC-2026-2087"],"provenance":"source"}],"euvd":{"id":"EUVD-2026-42024","exploited":false,"provenance":"source"},"lineage":{"familyId":"fam-apache-airflow-cve-2026-48828","children":[{"from":"CVE-2026-48892","to":"CVE-2026-65017","relation":"related","confidence":"high","kind":"lineage","evidence":[{"kind":"osv-related","provenance":"source","id":"GHSA-c56v-8w4g-3mfm","via":"reference","url":"https://www.cve.org/CVERecord?id=CVE-2026-48892"},{"kind":"osv-related","provenance":"source","id":"PYSEC-2026-3993","via":"reference","url":"https://www.cve.org/CVERecord?id=CVE-2026-48892"}]}]}}
