Descriptions

Electron is a framework which lets you write cross-platform desktop applications using JavaScript, HTML and CSS. A Content-Security-Policy that disables eval, specifically setting a `script-src` directive and _not_ providing `unsafe-eval` in that directive, is not respected in renderers that have sandbox disabled. i.e. `sandbox: false` in the `webPreferences` object. This allows usage of methods like `eval()` and `new Function` unexpectedly which can result in an expanded attack surface. This issue only ever affected the 22 and 23 major versions of Electron and has been fixed in the latest versions of those release lines. Specifically, these versions contain the fixes: 22.0.1 and 23.0.0-alpha.2 We recommend all apps upgrade to the latest stable version of Electron. If upgrading isn't possible, this issue can be addressed without upgrading by enabling `sandbox: true` on all renderers.

Electron es un framework que le permite escribir aplicaciones de escritorio multiplataforma utilizando JavaScript, HTML y CSS. Una política de seguridad de contenido que deshabilita la evaluación, específicamente estableciendo una directiva `script-src` y _no_ proporcionando `unsafe-eval` en esa directiva, no se respeta en los renderizadores que tienen la zona de pruebas deshabilitada. es decir, `sandbox: false` en el objeto `webPreferences`. Esto permite el uso inesperado de métodos como `eval()` y `new Function`, lo que puede resultar en una superficie de ataque ampliada. Este problema solo afectó a las versiones principales 22 y 23 de Electron y se solucionó en las últimas versiones de esas líneas de lanzamiento. Específicamente, estas versiones contienen las correcciones: 22.0.1 y 23.0.0-alpha.2. Recomendamos que todas las aplicaciones actualicen a la última versión estable de Electron. Si no es posible realizar la actualización, este problema se puede solucionar sin realizar la actualización habilitando `sandbox: true` en todos los renderizadores.
