CVE-2026-22181: OpenClaw's web tools strict URL guard could lose DNS pinning when env proxy is configured
(updated )
openclaw web tools strict URL fetch paths could lose DNS pinning when environment proxy variables are configured (HTTP_PROXY/HTTPS_PROXY/ALL_PROXY, including lowercase variants).
In affected builds, strict URL checks (for example web_fetch and citation redirect resolution) validated one destination during SSRF guard checks, but runtime connection routing could proceed through an env-proxy dispatcher.
