{"id":"BIT-airflow-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.","aliases":["CVE-2026-45192","GHSA-2883-wwh7-x57v","PYSEC-2026-173"],"modified":"2026-09-08T08:45:27.077827948Z","published":"2026-06-05T05:40:43.901Z","database_specific":{"severity":"Medium","cpes":["cpe:2.3:a:apache:airflow:*:*:*:*:*:*:*:*"]},"references":[{"type":"ADVISORY","url":"http://www.openwall.com/lists/oss-security/2026/06/01/3"},{"type":"FIX","url":"https://github.com/apache/airflow/pull/66673"},{"type":"ADVISORY","url":"https://lists.apache.org/thread/r2q93dg2wp5h9sd9vh6y4y5ljqd9crdd"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-45192"}],"affected":[{"package":{"name":"airflow","ecosystem":"Bitnami","purl":"pkg:bitnami/airflow"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"3.2.2"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/airflow/BIT-airflow-2026-45192.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"}
