{"schema_version": "1.6.1", "id": "CVE-2026-40961", "summary": "Open Redirect Bypass Vulnerability", "details": "A bug in the login redirect route in Apache Airflow allowed authenticated users to craft URLs that bypassed the `is_safe_url` check, enabling redirection from a trusted Airflow domain to an attacker-controlled origin. Users are advised to upgrade to `apache-airflow` 3.2.2 or later. As a defense-in-depth mitigation, deployment operators can place Airflow behind a reverse proxy that strips off-domain `next=` query parameters before they reach the login endpoint.", "affected": [{"ranges": [{"type": "SEMVER", "events": [{"introduced": "3.0.0"}, {"fixed": "3.2.2"}]}]}], "references": [{"type": "WEB", "url": "https://github.com/apache/airflow/pull/65557"}, {"type": "WEB", "url": "https://lists.apache.org/thread/qmt8ksh7gty6b8hr9w294t94j36jdv1q"}]}
