CVE-2026-28395: OpenClaw's Chrome extension relay binds publicly due to wildcard treated as loopback
(updated )
The Chrome extension relay (ensureChromeExtensionRelayServer) previously treated wildcard hosts (0.0.0.0 / ::) as loopback, which could make it bind the relay HTTP/WS server to all interfaces when a wildcard cdpUrl was passed.
