CVE-2026-33858

Dag Authors, who normally should not be able to execute code in the webserver context could craft XCom payload causing the webserver to execute arbitrary code. Since Dag Authors are already highly trusted, severity of this issue is Low. Users are recommended to upgrade to Apache Airflow 3.2.0, which resolves this issue.

Summary		(es) Autores de DAGs, quienes normalmente no deberían poder ejecutar código en el contexto del servidor web, podrían crear una carga útil de XCom haciendo que el servidor web ejecute código arbitrario. Dado que los Autores de DAGs ya son de alta confianza, la severidad de este problema es Baja. Se recomienda a los usuarios actualizar a Apache Airflow 3.2.0, que resuelve este problema.
