      "value": "Mantis Bug Tracker (MantisBT) is an open source issue tracker. In versions 2.11.0 through 2.28.1, a Stored XSS vulnerability is caused by incorrect escaping of a saved filter's owner, allowing an attacker to inject arbitrary HTML on systems where $g_show_user_realname = ON. Note that By default, only users with Manager access level or above can save their filters publicly. This issue has been fixed in version 2.28.2. If developers are unable to update immediately, they can work around this issue by preventing display of users' real names (set $g_ show_user_realname = OFF; in configuration), and restricting the ability to store filters (set $g_stored_query_create_threshold / $g_stored_query_create_shared_threshold to NOBODY)."

En las versiones 2.11.0 a 2.28.1, una vulnerabilidad de XSS Almacenado es causada por el escape incorrecto del propietario de un filtro guardado, permitiendo a un atacante inyectar HTML arbitrario en sistemas donde $g_show_user_realname = ON. Tenga en cuenta que, por defecto, solo los usuarios con nivel de acceso de Gerente o superior pueden guardar sus filtros públicamente. Este problema ha sido solucionado en la versión 2.28.2. Si los desarrolladores no pueden actualizar inmediatamente, pueden solucionar este problema evitando la visualización de los nombres reales de los usuarios (establezca $g_ show_user_realname = OFF; en la configuración), y restringiendo la capacidad de almacenar filtros (establezca $g_stored_query_create_threshold / $g_stored_query_create_shared_threshold en NOBODY)."
