      "value": "Streambert is a cross-platform Electron Desktop App to stream and download video content. From version 2.5.0 until version 2.6.0, the wyzie-open-redeem IPC handler in index.js creates the partition:wyzie-redeem Electron session and registers an onHeadersReceived hook that removes the Content-Security-Policy header from every response in that session. The redeem window also lacks a setWindowOpenHandler restriction, so script injection in sub.wyzie.io, a loaded third-party resource, or a site reached through navigation executes without CSP constraints and can affect additional windows and persistent session storage. A user must open the Wyzie API key redemption window, and exploitation requires attacker-controlled script content in a loaded page. The resulting renderer script can invoke renderer-exposed application functionality and can be chained with other vulnerabilities to access internal services or sensitive data. This issue is fixed in version 2.6.0."

      "value": "Streambert es una aplicación de escritorio Electron multiplataforma para transmitir y descargar contenido de video. Desde la versión 2.5.0 hasta la versión 2.6.0, el gestor IPC wyzie-open-redeem en index.js crea la sesión Electron partition:wyzie-redeem y registra un hook onHeadersReceived que elimina el encabezado Content-Security-Policy de cada respuesta en esa sesión. La ventana de canje también carece de una restricción setWindowOpenHandler, por lo que la inyección de scripts en sub.wyzie.io, un recurso de terceros cargado, o un sitio alcanzado a través de la navegación se ejecuta sin restricciones de CSP y puede afectar a ventanas adicionales y al almacenamiento persistente de la sesión. Un usuario debe abrir la ventana de canje de clave de API de Wyzie, y la explotación requiere contenido de script controlado por el atacante en una página cargada. El script de renderizado resultante puede invocar la funcionalidad de la aplicación expuesta al renderizador y puede encadenarse con otras vulnerabilidades para acceder a servicios internos o datos sensibles. Este problema está solucionado en la versión 2.6.0."
