Received Received - Intake
SSRF Bypass via Incomplete IPv4 Validation in OpenClaw

Publication date: 2026-03-19

Last updated on: 2026-04-20

Assigner: VulnCheck

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.

Executive Summary

This vulnerability exists in OpenClaw versions prior to 2026.2.22 due to incomplete validation of IPv4 special-use ranges in the isPrivateIpv4() function.

Because of this incomplete validation, requests to RFC-reserved IPv4 ranges can bypass Server-Side Request Forgery (SSRF) policy checks.

Attackers who have network access to these special-use IPv4 ranges can exploit the web_fetch functionality to access addresses that should be blocked, such as the 198.18.0.0/15 range and other non-global IP ranges.

Impact Analysis

This vulnerability can allow an attacker with network reachability to special-use IPv4 ranges to bypass SSRF protections and access internal or otherwise restricted network resources.

Such unauthorized access could lead to information disclosure, unauthorized interactions with internal services, or further exploitation depending on the network environment.
