Summary OpenClaw's web tools strict URL guard could lose DNS pinning when env proxy is configured `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.
