Las versiones 3.6.14 y anteriores contienen una vulnerabilidad de Denegaci\u00f3n de Servicio (DoS) en la funcionalidad de entrada del t\u00edtulo debido a una falta de validaci\u00f3n de longitud adecuada. Esta falla permite a un atacante causar un error de falta de memoria (OOM) y la terminaci\u00f3n subsiguiente del programa al insertar una cadena excesivamente larga en el t\u00edtulo de una nota. Esto puede ser activado ya sea a trav\u00e9s de la entrada directa de la interfaz de usuario (UI) o program\u00e1ticamente a trav\u00e9s de la API del servicio web local despu\u00e9s de comprometer un token de autenticaci\u00f3n. Hay 2 m\u00e9todos principales de explotaci\u00f3n: a trav\u00e9s de la Entrada de Interfaz de Usuario (UI), y la API del Servicio Web Local. Un usuario local puede escribir o pegar directamente una cadena extremadamente larga en el campo del t\u00edtulo al crear o editar una nota. Joplin ejecuta un servicio web local (t\u00edpicamente en el puerto 41184) que permite la interacci\u00f3n program\u00e1tica, como crear o editar notas a trav\u00e9s de llamadas a la API HTTP. Si un atacante logra exfiltrar o comprometer el token de autenticaci\u00f3n del usuario (por ejemplo, a trav\u00e9s de malware en el sistema local, u otras vulnerabilidades locales), entonces puede enviar una solicitud HTTP POST manipulada a esta API local. Al incluir una cadena excesivamente larga en el par\u00e1metro del t\u00edtulo de esta solicitud, la aplicaci\u00f3n intentar\u00e1 asignar una cantidad ilimitada de memoria.
