OpenClaw < 2026.2.22 - Incomplete IPv4 Special-Use Range Blocking in SSRF Guard

Published Mar 19, 2026 CVSS 4.0 · 2.3 Low EPSS < 1% KEV · Not listed
Description
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 web_fetch functionality to access blocked addresses such as 198.18.0.0/15 and other non-global ranges.
