An attacker with a low-privileged account (e.g., Student) can inject arbitrary JavaScript payloads into a comment. When any other user (Student, Teacher, or Admin) views the annotated PDF, the payload is executed in their browser, leading to session hijacking, credential theft, or other attacker-controlled actions."

Un atacante con una cuenta de bajo privilegio (p. ej., Estudiante) puede inyectar cargas útiles JavaScript arbitrarias en un comentario. Cuando cualquier otro usuario (Estudiante, Profesor o Administrador) ve el PDF anotado, la carga útil se ejecuta en su navegador, lo que lleva al secuestro de sesión, robo de credenciales u otras acciones controladas por el atacante."
