SvelteKit is a framework for rapidly developing robust, performant web applications using Svelte. Prior to 2.70.2, the content negotiation header parser used by SvelteKit's request handling (for headers such as Accept) uses a regular expression vulnerable to quadratic backtracking, so a maliciously crafted header value can cause excessive CPU consumption and degrade or deny service. Version 2.70.2 fixes the issue.

 https://cve.radiocsirt.org/vuln/ghsa-29g2-3rmr-qm68 GHSA-29g2-3rmr-qm68 — SvelteKit: ReDoS (O(n^2)) in content negotiation — unauthenticated DoS via the Accept header 2026-10-06T04:17:46.199171+00:00

Affected: npm: @sveltejs/kit

### Impact SvelteKit is vulnerable to remote CPU-exhaustion DoS attacks via specifically-crafted `Accept` headers. The impact is mitigated by default header length limits on most platforms, but in the case of raised or absent limits a denial of service is possible.

### Patches The vulnerability is patched in `@sveltejs/kit` version 2.70.2.
