{"id":"BIT-airflow-2026-68969","summary":"Apache Airflow: Bulk Variable and Connection endpoints record secret values in the audit log in cleartext","details":"Apache Airflow wrote Variable values and Connection `extra` contents to the audit log in cleartext when they were submitted through the bulk endpoints (`PATCH /api/v2/variables` and `PATCH /api/v2/connections`). The audit-log masking recognised only top-level request fields, and a bulk request nests its entities two levels below, so no masking was applied to them. Any authenticated user with audit-log read access -- who need not hold Variables or Connections read at all -- could recover those secrets verbatim, and the Connection `extra` copy is stored unencrypted in the log while the connection table encrypts it. The Airflow UI's *Import Variables* action posts to this endpoint, so an ordinary operator import wrote every secret in the file to the log. This is a different code path from CVE-2026-50204: that fix shipped in 3.3.0 and covers the single-entity endpoints only, so deployments that upgraded in response to that advisory remain affected and must upgrade again. Users are advised to upgrade to apache-airflow 3.3.1 or later.","aliases":["CVE-2026-68969","PYSEC-2026-3711"],"modified":"2026-09-08T08:45:27.653231532Z","published":"2026-08-17T05:39:30.582Z","database_specific":{"cpes":["cpe:2.3:a:apache:airflow:*:*:*:*:*:*:*:*"],"severity":"Medium"},"references":[{"type":"FIX","url":"https://github.com/apache/airflow/pull/70890"},{"type":"DISCUSSION","url":"https://lists.apache.org/thread/p3jr90jgp2brto4vwcrx680f3x11y70c"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-68969"},{"type":"WEB","url":"https://www.cve.org/CVERecord?id=CVE-2026-50204"}],"affected":[{"package":{"name":"airflow","ecosystem":"Bitnami","purl":"pkg:bitnami/airflow"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"3.3.1"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/airflow/BIT-airflow-2026-68969.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"}
