Se ha detectado una vulnerabilidad de uso despu\u00e9s de liberaci\u00f3n (escritura) en versiones de Poppler anteriores a la 25.10.0 dentro de la clase StructTreeRoot. El problema surge del uso de punteros crudos a elementos de un 'std::vector', lo que puede llevar a punteros colgantes cuando el vector se redimensiona. La vulnerabilidad se origina en la forma en que refToParentMap almacena referencias a elementos de 'std::vector' utilizando punteros crudos. Estos punteros pueden volverse inv\u00e1lidos cuando el vector se redimensiona. Esta vulnerabilidad es un problema de seguridad com\u00fan que implica el uso de punteros crudos a 'std::vectors'. Internamente, 'std::vector' almacena sus elementos en un array asignado din\u00e1micamente. Cuando el array alcanza su capacidad y se a\u00f1ade un nuevo elemento, el vector reasigna un bloque de memoria m\u00e1s grande y mueve todos los elementos existentes a la nueva ubicaci\u00f3n. En este punto, si se almacenan punteros a elementos antes de que ocurra un redimensionamiento, se convierten en punteros colgantes una vez que ocurre la reasignaci\u00f3n.
