{"id":"GHSA-3qmm-r55x-hpxx","summary":"Apache Airflow secrets in rendered templates could contain parts of sensitive values when truncated","details":"In Apache Airflow versions before 3.1.6, when rendered template fields in a Dag exceed [core] max_templated_field_length, sensitive values could be exposed in cleartext in the Rendered Templates UI. This occurred because serialization of those fields used a secrets masker instance that did not include user-registered mask_secret() patterns, so secrets were not reliably masked before truncation and display.\n\nUsers are recommended to upgrade to 3.1.6 or later, which fixes this issue","aliases":["BIT-airflow-2025-68438","CVE-2025-68438","PYSEC-2026-9"],"modified":"2026-07-17T21:14:36.773441097Z","published":"2026-01-16T12:30:25Z","database_specific":{"severity":"HIGH","github_reviewed":true,"github_reviewed_at":"2026-01-16T20:59:54Z","nvd_published_at":"2026-01-16T11:16:03Z","cwe_ids":["CWE-200"]},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-68438"},{"type":"PACKAGE","url":"https://github.com/apache/airflow"},{"type":"WEB","url":"https://github.com/pypa/advisory-database/tree/main/vulns/apache-airflow/PYSEC-2026-9.yaml"},{"type":"WEB","url":"https://lists.apache.org/thread/55n7b4nlsz3vo5n4h5lrj9bfsk8ctyff"},{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2026/01/15/5"}],"affected":[{"package":{"name":"apache-airflow","ecosystem":"PyPI","purl":"pkg:pypi/apache-airflow"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.1.0"},{"fixed":"3.1.6"}]}],"versions":["3.1.0","3.1.1","3.1.1rc1","3.1.1rc2","3.1.2","3.1.2rc1","3.1.2rc2","3.1.3","3.1.3rc1","3.1.4","3.1.4rc1","3.1.4rc2","3.1.5","3.1.5rc1","3.1.6rc1"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/01/GHSA-3qmm-r55x-hpxx/GHSA-3qmm-r55x-hpxx.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"}]}
