GHSA-8266-84wp-wv5c: Svelte has a potential mXSS vulnerability due to improper HTML escaping

### Summary A potential XSS vulnerability exists in Svelte for versions prior to 4.2.19. ### Details Svelte improperly escapes HTML on server-side rendering. It converts strings according to the following rules: - If the string is an attribute value: - `"` -> `&quot;` - `&` -> `&amp;` - Other characters -> No conversion - Otherwise: - `<` -> `&lt;` - `&` -> `&amp;` - Other characters -> No conversion 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. More specifically, this can occur when injecting malicious content into an attribute within a `<noscript>` tag. ### PoC A vulnerable page (`+page.svelte`): ```html <script> import { page } from "$app/stores" // user input let href = $page.url.searchParams.get("href") ?? "https://example.com"; </script> <noscript> <a href={href}...
