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

CVE-2026-66062 / GHSA-29g2-3rmr-qm68

More information

Details

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.

Severity

• CVSS Score: 5.3 / 10 (Medium)
• Vector String: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L
