CVE-2026-25917

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 fixes the issue.

Summary		(es) Autores de Dag, quienes normalmente no deberían poder ejecutar código en el contexto del servidor web, podrían crear una carga útil de XCom que provoque que el servidor web ejecute código arbitrario. Dado que los Autores de Dag ya gozan de gran confianza, la gravedad de este problema es Baja. Se recomienda a los usuarios actualizar a Apache Airflow 3.2.0, que corrige el problema.
