CVE-2026-30827

A flaw was found in express-rate-limit. The default key generator incorrectly applies IPv6 subnet masking to IPv4-mapped IPv6 addresses, which are used when an IPv4 client connects to a dual-stack server. This misconfiguration causes all IPv4 traffic to be treated as a single entity for rate...

CVE-2025-41759

An administrator may attempt to block all networks by specifying "" or "all" as the network identifier. However, these values are not supported and do not trigger any validation error. Instead, they are silently interpreted as network 0 which results in no networks being blocked at all...

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...

CVE-2026-30827 express-rate-limit: IPv4-mapped IPv6 addresses bypass per-client rate limiting (all IPv4 clients share one bucket on dual-stack servers)

express-rate-limit is a basic rate-limiting middleware for Express. In versions starting from 8.0.0 and prior to versions 8.0.2, 8.1.1, 8.2.2, and 8.3.0, the default keyGenerator in express-rate-limit applies IPv6 subnet masking /56 by default to all addresses that net.isIPv6 returns true for. Th...

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...
