OpenClaw < 2026.4.10 - DNS Rebinding SSRF via Hostname Validation Bypass

Type: advisorySources: OSV

OpenClaw before 2026.4.10 contains a server-side request forgery vulnerability in browser navigation policy that allows attackers to bypass hostname validation through DNS rebinding attacks. Attackers can exploit inconsistent hostname resolution between validation and actual network requests to pivot to internal resources via unallowlisted hostname URLs.
