{"id":"CVE-2026-68969","state":"PUBLISHED","title":"Apache Airflow: Bulk Variable and Connection endpoints record secret values in the audit log in cleartext","description":"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.","publishedAt":"2026-08-12T15:26:40.095Z","updatedAt":"2026-09-16T14:57:12.666Z","severity":{"score":6.5,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","source":"CISA-ADP"},"assigner":"apache","products":["Apache Software Foundation Apache Airflow"],"affected":[{"vendor":"Apache Software Foundation","product":"Apache Airflow","packageName":"apache-airflow","packageURL":"pkg:pypi/apache-airflow","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThan":"3.3.1","versionType":"semver"}],"collectionURL":"https://pypi.python.org"}],"references":["https://github.com/apache/airflow/pull/70890","https://lists.apache.org/thread/p3jr90jgp2brto4vwcrx680f3x11y70c","https://www.cve.org/CVERecord?id=CVE-2026-50204"],"weaknesses":["CWE-532"],"ingestedAt":"2026-10-29T20:12:49.727Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/68xxx/CVE-2026-68969.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-68969","state":"PUBLISHED","datePublished":"2026-08-12T15:26:40.095Z","dateUpdated":"2026-09-16T14:57:12.666Z","assignerShortName":"apache","assignerOrgId":"f0158376-9dc2-43b6-827c-5f631a4d8d09","dateReserved":"2026-08-01T03:22:13.493Z"},"containers":{"cna":{"title":"Apache Airflow: Bulk Variable and Connection endpoints record secret values in the audit log in cleartext","descriptions":[{"lang":"en","value":"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`).
