CVE-2026-22181 PUBLISHED

OpenClaw < 2026.3.2 - DNS Pinning Bypass via Environment Proxy Configuration in web_fetch

Assigner: VulnCheck
Reserved: 06.01.2026 Published: 18.03.2026 Updated: 18.03.2026

OpenClaw versions prior to 2026.3.2 contain a DNS pinning bypass vulnerability in strict URL fetch paths that allows attackers to circumvent SSRF guards when environment proxy variables are configured. When HTTP_PROXY, HTTPS_PROXY, or ALL_PROXY environment variables are present, attacker-influenced URLs can be routed through proxy behavior instead of pinned-destination routing, enabling access to internal targets reachable from the proxy environment.
