{"id":"CVE-2026-45192","aliases":["BIT-airflow-2026-45192","GHSA-2883-wwh7-x57v","PYSEC-2026-173"],"url":"https://o3.security/vulnerability/CVE-2026-45192","summary":"Apache Airflow: Incomplete Redaction of Sensitive Fields in Connection Extra API Response","details":"A bug in the GET `/api/v2/connections/{connection_id}` REST API endpoint in Apache Airflow allowed an authenticated UI/API user with Connection-read permission to retrieve secrets stored in a Connection's `extra` JSON blob under field names not present in the redaction allowlist (`DEFAULT_SENSITIVE_FIELDS`) — for example, official Slack-provider credential field names were returned in plaintext. Affects deployments that store credentials in Connection `extra` blobs and grant Connection-read access to multiple users. Users are advised to upgrade to `apache-airflow` 3.2.2 or later. As a defense-in-depth mitigation, deployment operators can store sensitive credential values in a secret-backend rather than inlined into the Connection's `extra` field.","published":"2026-06-01T06:51:41.026Z","modified":"2026-08-12T03:51:42.517439470Z","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":0.00425,"percentile":0.35214,"asOf":"2026-08-24"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"PyPI","name":"apache-airflow","fixedVersion":"3.2.2"}],"fix":{"url":"https://github.com/apache/airflow/pull/66673","label":"apache/airflow#66673"},"references":[{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2026/06/01/3"},{"type":"WEB","url":"https://pypi.python.org"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/45xxx/CVE-2026-45192.json"},{"type":"ADVISORY","url":"https://lists.apache.org/thread/r2q93dg2wp5h9sd9vh6y4y5ljqd9crdd"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-45192"},{"type":"FIX","url":"https://github.com/apache/airflow/pull/66673"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:42.517439470Z"}}
