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.
