CVE-2026-30827

CVE-2026-30827 affects express-rate-limit for Express. The default keyGenerator mishandles IPv4 when the system treats IPv4 addresses as IPv6 mapped (IPv4-mapped IPv6 addresses like ::ffff:x.x.x.x). On dual-stack servers, this causes a /56 subnet mask to be applied to all IPv6 addresses, making a...

express-rate-limit: IPv4-mapped IPv6 addresses bypass per-client rate limiting on servers with dual-stack network

Summary The default keyGenerator in express-rate-limit applies IPv6 subnet masking /56 by default to all addresses that net.isIPv6 returns true for. This includes IPv4-mapped IPv6 addresses ::ffff:x.x.x.x, which Node.js returns as request.ip on dual-stack servers. Because the first 80 bits of all...
