In Eclipse Jetty 9.4.6.v20170531 to 9.4.36.v20210114 inclusive, 10.0.0, and 11.0.0 when Jetty handles a request containing multiple Accept headers with a large number of “quality” i.e. q parameters, the server may enter a denial of service DoS state due to high CPU usage processing those quality...

SvelteKit: ReDoS (O(n^2)) in content negotiation — unauthenticated DoS via the Accept header

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 ...

CVE-2026-66062 SvelteKit: ReDoS (O(n^2)) in content negotiation — unauthenticated DoS via the Accept header

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...
