Ten en cuenta que como esta p\u00e1gina no presenta una comprobaci\u00f3n de tipo CSRF es bastante f\u00e1cil llevar a cabo muchas de esas peticiones. ### Parches Este problema ha sido parcheado en XWiki versiones 12.10.5 y 13.2RC1. Se proporcionan dos parches diferentes: - uno para corregir el problema de CSRF - otro m\u00e1s complejo que ahora es basado en el env\u00edo de un correo electr\u00f3nico para el proceso Forgot username. ### Mitigaciones Es posible arreglar el problema sin actualizar al editar la p\u00e1gina de ForgotUsername en versiones anteriores a 13.x, para usar el siguiente c\u00f3digo: https://github.com/xwiki/xwiki-platform/blob/69548c0320cbd772540cf4668743e69f879812cf/xwiki-platform-core/xwiki-platform-administration/xwiki-platform-administration-ui/src/main/resources/XWiki/ForgotUsername.xml#L39-L123 En la versi\u00f3n posterior a 13.x tambi\u00e9n es posible editar manualmente el archivo forgotusername.vm, pero es recomendado actualizar la versi\u00f3n aqu\u00ed.
