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","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","score":7.5},"cwes":["CWE-200"],"references":["https://lists.apache.org/thread/55n7b4nlsz3vo5n4h5lrj9bfsk8ctyff","http://www.openwall.com/lists/oss-security/2026/01/15/5"],"products":["apache:airflow"],"source":"nvd","synced_at":"2026-10-19T22:21:16.563232421+00:00"},"epss":{"cve":"CVE-2025-68438","score":0.00616,"percentile":0.49519,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-3qmm-r55x-hpxx","url":"https://osv.dev/vulnerability/GHSA-3qmm-r55x-hpxx","summary":"Apache Airflow secrets in rendered templates could contain parts of sensitive values when truncated","modified":"2026-09-10T03:50:58.819445976Z","packages":[{"ecosystem":"PyPI","name":"apache-airflow","purl":"pkg:pypi/apache-airflow","ranges":[">=3.1.0 <3.1.6"],"fixed":["3.1.6"]}]},{"id":"PYSEC-2026-9","url":"https://osv.dev/vulnerability/PYSEC-2026-9","summary":"","modified":"2026-06-10T17:00:29.974499745Z","packages":[{"ecosystem":"PyPI","name":"apache-airflow","purl":"pkg:pypi/apache-airflow","ranges":[">=3.1.0 <3.1.6"],"fixed":["3.1.6"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
