Summary		(es) Joplin es una aplicación de código abierto y gratuita para tomar notas y realizar tareas pendientes. Joplin no tiene en cuenta que un "<" seguido de un carácter que no sea una letra no se considerará HTML. Por lo tanto, es posible realizar un XSS colocando una etiqueta "ilegal" dentro de otra etiqueta.
