A DAG author whose code reaches the scheduler — the default on single-host deployments where the DAG bundle is importable from the scheduler process — could embed a custom `DeadlineReference` whose serialized form named an attacker-controlled module path, causing the scheduler to `import_string(...)` and instantiate that class with a live SQLAlchemy session attached. Affects deployments where DAG-author code is less trusted than the scheduler process. Users are advised to upgrade to `apache-airflow` 3.2.2 or later.","epss":{"date":"2026-11-02","percentile":0.52227,"score":0.00676},"exploits":[],"kev":null,"metrics":[{"score":7.3,"severity":"high","source":"ADP: CISA-ADP","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L","version":"3.1"}],"modifiedAt":1793688993203,"publishedAt":1780300093287,"references":[{"source":"CNA: apache","tags":["patch"],"url":"https://github.com/apache/airflow/pull/66737"},{"source":"CNA: apache","tags":["vendor-advisory"],"url":"https://lists.apache.org/thread/q227dghjwgfz8xsxrf2pwpz4wk43zm83"},{"source":"ADP: CVE","tags":[],"url":"http://www.openwall.com/lists/oss-security/2026/05/31/12"}],"remediation":[{"kind":"fix","source":"CNA: apache","text":"The reporting source identifies this reference as a patch.
