"value": "svelte performance oriented web framework. A potential mXSS vulnerability exists in Svelte for versions up to but not including 4.2.19. Svelte improperly escapes HTML on server-side rendering. The assumption is that attributes will always stay as such, but in some situation the final DOM tree rendered on browsers is different from what Svelte expects on server-side rendering. This may be leveraged to perform XSS attacks, and a type of the XSS is known as mXSS (mutation XSS). More specifically, this can occur when injecting malicious content into an attribute within a `noscript` tag. This issue has been addressed in release version 4.2.19. Users are advised to upgrade. There are no known workarounds for this vulnerability."

"value": "Svelte es un framework web orientado al rendimiento. Existe una vulnerabilidad potencial mXSS en Svelte para las versiones hasta la 4.2.19, pero no incluida. Svelte escapa incorrectamente el HTML en la representaci\u00f3n del lado del servidor. Se supone que los atributos siempre permanecer\u00e1n como tales, pero en algunas situaciones el \u00e1rbol DOM final representado en los navegadores es diferente de lo que Svelte espera en la representaci\u00f3n del lado del servidor. Esto se puede aprovechar para realizar ataques XSS, y un tipo de XSS se conoce como mXSS (XSS de mutaci\u00f3n). M\u00e1s espec\u00edficamente, esto puede ocurrir cuando se inyecta contenido malicioso en un atributo dentro de una etiqueta `noscript`. Este problema se ha solucionado en la versi\u00f3n de lanzamiento 4.2.19. Se recomienda a los usuarios que actualicen. No existen workarounds para esta vulnerabilidad."
