Deployments that co-locate multiple Dags in a single file and rely on per-DAG access control to limit source visibility are affected; single-Dag-per-file deployments are not. Upgrade to apache-airflow 3.3.0 or later.","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-639"],"references":["https://github.com/apache/airflow/pull/67662","https://lists.apache.org/thread/qqv41t3oydkn9o14r2rfz1wkdrsp5jzn","http://www.openwall.com/lists/oss-security/2026/07/07/5"],"products":["apache:airflow"],"source":"nvd","synced_at":"2026-10-25T23:44:34.550481224+00:00"},"epss":{"cve":"CVE-2026-49296","score":0.00601,"percentile":0.48442,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-4fh7-7jx4-8f6c","url":"https://osv.dev/vulnerability/GHSA-4fh7-7jx4-8f6c","summary":"apache-airflow DAG source authorization bypass exposes co-located DAG source","modified":"2026-08-12T19:40:41.031201224Z","packages":[{"ecosystem":"PyPI","name":"apache-airflow","purl":"pkg:pypi/apache-airflow","ranges":["<3.3.0"],"fixed":["3.3.0"]}]},{"id":"PYSEC-2026-2083","url":"https://osv.dev/vulnerability/PYSEC-2026-2083","summary":"","modified":"2026-08-19T12:15:03.331757781Z","packages":[{"ecosystem":"PyPI","name":"apache-airflow","purl":"pkg:pypi/apache-airflow","ranges":["<3.3.0"],"fixed":["3.3.0"]}]}],"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).
