A user allowed to create but not edit connections could overwrite a connection someone else had created in the meantime. Only deployments that enable the non-default `[core] test_connection` setting are affected. Users are advised to upgrade to apache-airflow 3.4.0 or later.","epss":null,"exploits":[],"kev":null,"metrics":[],"modifiedAt":1794215240025,"publishedAt":1794215193573,"references":[{"source":"CNA: apache","tags":["patch"],"url":"https://github.com/apache/airflow/pull/74837"},{"source":"CNA: apache","tags":["vendor-advisory"],"url":"https://lists.apache.org/thread.html/j3tqo8wd53mcyvkkw4z5pnt9tckks0j2"},{"source":"ADP: CVE","tags":[],"url":"http://www.openwall.com/lists/oss-security/2026/11/09/18"}],"remediation":[{"kind":"fix","source":"CNA: apache","text":"The reporting source identifies this reference as a patch.
