CVE-2026-100574 · Severity: medium · CVSS 5.9 · Published 2026-09-26

OpenClaw is a JavaScript library that fetches and validates network requests. A flaw in its DNS validation for trusted hostnames allows attackers who control DNS to trick the library into connecting to services on a computer's internal loopback network (127.0.0.1), bypassing security checks. This could expose sensitive data from internal services that should not be accessible.

## Technical details

OpenClaw's trusted-host DNS recheck validation fails to reject unspecified addresses (0.0.0.0, ::) when a trusted hostname resolves to them, enabling SSRF. An attacker with DNS influence can cause guarded fetches to reach loopback-bound services, achieving information disclosure. This requires high complexity (DNS hijacking) but impacts confidentiality; patched in 2026.8.1.
