Summary

OpenClaw's Chrome extension relay binds publicly due to wildcard treated as loopback

Details

Summary

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.

Impact

If configured with a wildcard cdpUrl, relay HTTP endpoints could become reachable off-host, leaking service presence/port and enabling DoS/brute-force traffic against the relay token header.

CVE-2026-28395 (GCVE-0-2026-28395)

Vulnerability from cvelistv5 – Published: 2026-03-05 21:59 – Updated: 2026-03-06 16:29

Title

OpenClaw 2026.1.14-1 < 2026.2.12 - Unintended Public Binding of Chrome Extension Relay via Wildcard cdpUrl

Summary

OpenClaw version 2026.1.14-1 prior to 2026.2.12 contain an improper network binding vulnerability in the Chrome extension (must be installed and enabled) relay server that treats wildcard hosts as loopback addresses, allowing the relay HTTP/WS server to bind to all interfaces when a wildcard cdpUrl is configured. Remote attackers can access relay HTTP endpoints off-host to leak service presence and port information, or conduct denial-of-service and brute-force attacks against the relay token header.
