      "value": "Indico is an event management system that uses Flask-Multipass, a multi-backend authentication system for Flask. In Indico prior to version 3.3.4, corresponding to Flask-Multipass prior to version 0.5.5, there is a Cross-Site-Scripting vulnerability during account creation when redirecting to the `next` URL. Exploitation requires initiating the account creation process with a maliciously crafted link, and then finalizing the signup process. Because of this, it can only target newly created (and thus unprivileged) Indico users. Indico 3.3.4 upgrades the dependency on Flask-Multipass to version 0.5.5, which fixes the issue. Those who build the Indico package themselves and cannot upgrade can update the `flask-multipass` dependency to `>=0.5.5` which fixes the vulnerability. Otherwise one could configure one's web server to disallow requests containing a query string with a `next` parameter that starts with `javascript:`."

      "value": "Indico es un sistema de gesti\u00f3n de eventos que utiliza Flask-Multipass, un sistema de autenticaci\u00f3n multi-backend para Flask. En Indico anterior a la versi\u00f3n 3.3.4, correspondiente a Flask-Multipass anterior a la versi\u00f3n 0.5.5, existe una vulnerabilidad de Cross-Site-Scripting durante la creaci\u00f3n de la cuenta al redireccionar a la URL `next`. La explotaci\u00f3n requiere iniciar el proceso de creaci\u00f3n de la cuenta con un enlace creado con fines malintencionados y luego finalizar el proceso de registro. Debido a esto, solo puede apuntar a usuarios de Indico reci\u00e9n creados (y por lo tanto sin privilegios). Indico 3.3.4 actualiza la dependencia de Flask-Multipass a la versi\u00f3n 0.5.5, que corrige el problema. Aquellos que construyen el paquete Indico ellos mismos y no pueden actualizar pueden actualizar la dependencia `flask-multipass` a `>=0.5.5` que corrige la vulnerabilidad. De lo contrario, uno podr\u00eda configurar su servidor web para rechazar solicitudes que contengan una cadena de consulta con un par\u00e1metro `next` que comience con `javascript:`."
