      "value": "Tauri is a framework for building binaries for all major desktop platforms. From 2.0 to 2.11.0, a flaw in Tauri's is_local_url() function causes it to incorrectly classify remote URLs as trusted local origins on Windows and Android. On these systems, Tauri maps custom URI scheme protocols to http://<scheme>.localhost/ because those platforms' WebView implementations cannot serve custom URI schemes directly. The issue is that Tauri's check to see if the origin is local, only checks the first subdomain of the URL. An attacker can abuse this by hosting a page on a domain whose subdomain matches the custom scheme of the application. This vulnerability is fixed in 2.10.3."

      "value": "Tauri es un framework para construir binarios para todas las principales plataformas de escritorio. Desde la 2.0 hasta la 2.11.0, un fallo en la función is_local_url() de Tauri hace que clasifique incorrectamente las URLs remotas como orígenes locales de confianza en Windows y Android. En estos sistemas, Tauri mapea los protocolos de esquema URI personalizados a http://[scheme].localhost/ porque las implementaciones de WebView de esas plataformas no pueden servir esquemas URI personalizados directamente. El problema es que la comprobación de Tauri para ver si el origen es local, solo comprueba el primer subdominio de la URL. Un atacante puede abusar de esto alojando una página en un dominio cuyo subdominio coincida con el esquema personalizado de la aplicación. Esta vulnerabilidad está corregida en la 2.10.3."
