EUVD-2026-13286

OpenClaw versions prior to 2026.2.22 contain incomplete IPv4 special-use range validation in the isPrivateIpv4 function, allowing requests to RFC-reserved ranges to bypass SSRF policy checks. Attackers with network reachability to special-use IPv4 ranges can exploit webfetch functionality to acce...

USN-8098-1: Linux kernel vulnerabilities

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...

The vulnerability of the tcp_add_backlog() function in the net/ipv4/tcp_ipv4.c module, which is part of the Linux operating system’s IPv4 protocol implementation, allows a hacker to cause a service failure.

The vulnerability of the tcpaddbacklog function in the net/ipv4/tcpipv4.c module, which is part of the Linux operating system’s IPv4 protocol implementation, involves integer overflow or cyclic shift vulnerabilities. Exploiting this vulnerability could allow a remote attacker to cause a service...

CVE-2026-26324 OpenClaw has a SSRF guard bypass via full-form IPv4-mapped IPv6 (loopback / metadata reachable)

OpenClaw is a personal AI assistant. Prior to version 2026.2.14, OpenClaw's SSRF protection could be bypassed using full-form IPv4-mapped IPv6 literals such as 0:0:0:0:0:ffff:7f00:1 which is 127.0.0.1. This could allow requests that should be blocked loopback / private network / link-local metada...
