The intent was to restrict access to sensitive connection fields to Connection Editing Users, effectively applying a \"write-only\" model for sensitive values.\n\n\nIn Airflow 3.0.3, this model was unintentionally violated: sensitive connection information could be viewed by users with READ permissions through both the API and the UI. This behavior also bypassed the `AIRFLOW__CORE__HIDE_SENSITIVE_VAR_CONN_FIELDS` configuration option.\n\n\nThis issue does not affect Airflow 2.x, where exposing sensitive information to connection editors was the intended and documented behavior.\n\n\n\n\n\n\nUsers of Airflow 3.0.3 are advised to upgrade Airflow to >=3.0.4.","published":"2025-09-26T07:28:59.066Z","modified":"2026-08-12T03:51:10.022945706Z","cvss":{"score":6.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N"},"epss":{"score":0.00914,"percentile":0.58405,"asOf":"2026-09-17"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"PyPI","name":"apache-airflow","fixedVersion":"3.0.4"}],"fix":null,"references":[{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2025/09/25/4"},{"type":"WEB","url":"https://pypi.python.org"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/54xxx/CVE-2025-54831.json"},{"type":"ADVISORY","url":"https://lists.apache.org/thread/vblmfqtydrp5zgn2q8tj3slk5podxspf"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-54831"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:10.022945706Z"}}
