Antes de la versi\u00f3n 25.4.0, la l\u00f3gica de procesamiento de recetas de conda-build era vulnerable a la ejecuci\u00f3n de c\u00f3digo arbitrario debido a la evaluaci\u00f3n insegura de los selectores de recetas. Actualmente, conda-build utiliza la funci\u00f3n eval para procesar selectores incrustados en archivos meta.yaml. Este enfoque eval\u00faa expresiones definidas por el usuario sin la debida depuraci\u00f3n, lo que permite la ejecuci\u00f3n de c\u00f3digo arbitrario durante el proceso de compilaci\u00f3n. Como resultado, se compromete la integridad del entorno de compilaci\u00f3n y se pueden realizar comandos u operaciones de archivo no autorizados. La vulnerabilidad se deriva del riesgo inherente de usar eval() en entradas no confiables en un contexto dise\u00f1ado para controlar configuraciones de compilaci\u00f3n din\u00e1micas. Al interpretar directamente las expresiones del selector, conda-build crea una posible v\u00eda de ejecuci\u00f3n para c\u00f3digo malicioso, violando las suposiciones de seguridad.
