Svelte SSR attribute spreading includes inherited properties from prototype chain
Résumé
Svelte SSR attribute spreading includes inherited properties from prototype chain
Description d'origine
La description telle que publiée par la source (souvent en anglais).
svelte performance oriented web framework. Prior to 5.51.5, in server-side rendering, attribute spreading on elements (e.g. ) enumerates inherited properties from the object's prototype chain rather than only own properties. In environments where Object.prototype has already been polluted — a precondition outside of Svelte's control — this can cause unexpected attributes to appear in SSR output or cause SSR to throw errors. Client-side rendering is not affected. This vulnerability is fixed in 5.51.5.
