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","published":"2026-01-16T10:06:08.128Z","modified":"2026-08-12T03:51:35.602690732Z","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"PyPI","name":"apache-airflow","fixedVersion":"3.1.6"}],"fix":null,"references":[{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2026/01/15/5"},{"type":"WEB","url":"https://pypi.python.org"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/68xxx/CVE-2025-68438.json"},{"type":"ADVISORY","url":"https://lists.apache.org/thread/55n7b4nlsz3vo5n4h5lrj9bfsk8ctyff"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-68438"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:35.602690732Z"}}
