A user allowed to trigger a Dag that uses a deadline alert with an asynchronous callback could pass a `conf` that, once the deadline was missed, either crashed the scheduler repeatedly or was rebuilt into objects inside the Triggerer. Users are advised to upgrade to apache-airflow 3.4.0 or later.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":["CWE-502"],"vendors":[],"products":[],"references":[{"url":"https://github.com/apache/airflow/pull/74834","tags":[]},{"url":"https://lists.apache.org/thread.html/qb4qxr40s0q6w9b9t5mfw5qf53pg97p3","tags":[]},{"url":"http://www.openwall.com/lists/oss-security/2026/11/09/13","tags":[]}],"exploitRefs":[{"url":"https://github.com/apache/airflow/pull/74834","tags":[]}],"hasPoc":true,"ai":null}
