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.","epss":{"date":"2026-11-02","percentile":0.51097,"score":0.00649},"exploits":[],"kev":null,"metrics":[{"score":7.2,"severity":"high","source":"ADP: CISA-ADP","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:N","version":"3.1"}],"modifiedAt":1793688901599,"publishedAt":1780300504647,"references":[{"source":"CNA: apache","tags":["patch"],"url":"https://github.com/apache/airflow/pull/65557"},{"source":"CNA: apache","tags":["vendor-advisory"],"url":"https://lists.apache.org/thread/qmt8ksh7gty6b8hr9w294t94j36jdv1q"},{"source":"ADP: CVE","tags":[],"url":"http://www.openwall.com/lists/oss-security/2026/05/31/2"}],"remediation":[{"kind":"fix","source":"CNA: apache","text":"The reporting source identifies this reference as a patch.
