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...

CVE-2026-30827: Allocation of Resources Without Limits or Throttling

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.

Allocation of Resources Without Limits or Throttling

Overview express-rate-limit is a Basic IP rate-limiting middleware for Express. Use to limit repeated requests to public APIs and/or endpoints such as password reset. Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling in the ipKeyGenerator...

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...

Allocation of Resources Without Limits or Throttling

Overview openclaw is a 🦞 OpenClaw — Personal AI Assistant Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling through improper handling of client IP address normalization in the authentication rate-limiting process. An attacker can increase the...

Vulnerability The hook authentication throttle keyed failed attempts by raw socket remoteAddress text. IPv4 and IPv4-mapped IPv6 forms of the same client for example 1.2.3.4 and ::ffff:1.2.3.4 were treated as different clients, allowing separate rate-limit buckets. Impact An attacker could split...

CVE-2026-27624

Coturn was vulnerable to a bypass of the IPv4-mapped IPv6 loopback/denied-peer-ip checks prior to 4.9.0. The root cause was that three functions in src/client/ns_turn_ioaddr.c did not check IN6_IS_ADDR_V4MAPPED, allowing a CreatePermission/ChannelBind with ::ffff:127.0.0.1 to bypass 127.0.0.0/8 l...
