Since the UI users are already highly trusted, this is a Low severity vulnerability.\n\nIt does not affect Airflow release - example_dags are not supposed to be enabled in production environment, however\nusers following the example could replicate the bad pattern. Documentation of Airflow 3.2.0 contains version of\nthe example with improved resiliance for that case.\n\nUsers who followed that pattern are advised to adjust their implementations accordingly.","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:H/A:N","score":8.1},"cwes":["CWE-94"],"references":["https://github.com/apache/airflow/pull/63200","https://lists.apache.org/thread/3mf4cfx070ofsnf9qy0s2v5gqb5sc2g1","http://www.openwall.com/lists/oss-security/2026/04/15/1"],"products":["apache:airflow"],"source":"nvd","synced_at":"2026-10-19T22:30:49.762551342+00:00"},"epss":{"cve":"CVE-2025-54550","score":0.00579,"percentile":0.47361,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-q2hg-643c-gw8h","url":"https://osv.dev/vulnerability/GHSA-q2hg-643c-gw8h","summary":"Apache Airflow: RCE by race condition in example_xcom dag","modified":"2026-07-13T16:43:26.827495526Z","packages":[{"ecosystem":"PyPI","name":"apache-airflow","purl":"pkg:pypi/apache-airflow","ranges":["<3.2.0"],"fixed":["3.2.0"]}]},{"id":"PYSEC-2026-2353","url":"https://osv.dev/vulnerability/PYSEC-2026-2353","summary":"Apache Airflow: RCE by race condition in example_xcom dag","modified":"2026-07-13T16:43:26.827495526Z","packages":[{"ecosystem":"PyPI","name":"apache-airflow","purl":"pkg:pypi/apache-airflow","ranges":["<3.2.0"],"fixed":["3.2.0"]}]}],"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).
