Users are advised to upgrade to apache-airflow 3.3.1 or later, which masks nested Variable values regardless of type.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","score":6.5},"cwes":["CWE-312"],"references":["https://github.com/apache/airflow/pull/68975","https://lists.apache.org/thread/fncod6vttfo5fvmfs3h9r8s2kmm9j1n6","http://www.openwall.com/lists/oss-security/2026/08/12/7"],"products":["apache:airflow"],"source":"nvd","synced_at":"2026-10-24T16:53:35.584907681+00:00"},"epss":{"cve":"CVE-2026-59244","score":0.0023,"percentile":0.13697,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-f643-3rc2-j27w","url":"https://osv.dev/vulnerability/GHSA-f643-3rc2-j27w","summary":"Apache Airflow exposes dict-valued var.json secrets in Rendered Templates","modified":"2026-10-02T23:40:45.182252028Z","packages":[{"ecosystem":"PyPI","name":"apache-airflow","purl":"pkg:pypi/apache-airflow","ranges":["<3.3.1"],"fixed":["3.3.1"]}]},{"id":"PYSEC-2026-3706","url":"https://osv.dev/vulnerability/PYSEC-2026-3706","summary":"","modified":"2026-10-15T14:45:05.420367192Z","packages":[{"ecosystem":"PyPI","name":"apache-airflow","purl":"pkg:pypi/apache-airflow","ranges":["<3.3.1"],"fixed":["3.3.1"]}]}],"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).
