公告说明

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.
