This advisory has been withdrawn because it is a duplicate of GHSA-27mw-82g8-phjj. This link is maintained to preserve external references.
SvelteKit (@sveltejs/kit) before 3.0.0 contains a cross-site scripting vulnerability in prerendered pages because a cache-control header value set via setHeaders is inserted without escaping into a <meta http-equiv="cache-control"> tag. An attacker who can influence that untrusted value at prerender time can break out of the content attribute and inject HTML or JavaScript that executes when users visit the page.
@sveltejs/kit < 3.0.0Refer to the advisory for the patched release.
