CVE-2026-6011Public exploitNetwork attack vector

Internal service access via unpinned DNS resolution

Published Apr 10, 2026 · Updated Apr 10, 2026

Server-side request forgery in OpenClaw Foundation OpenClaw before 2026.1.29 allows remote attackers to reach internal services. The fetchWithRedirects path validates a hostname with one DNS lookup, then fetches it with another, allowing DNS rebinding after the public-address check. Exploitation requires attacker-controlled DNS, low TTL and precise timing; successful requests can read metadata or other host-reachable services.
