Description

OpenClaw: Android accepted cleartext remote gateway endpoints and sent stored credentials over ws://

Summary

Before OpenClaw 2026.4.2, Android accepted non-loopback cleartext ws:// gateway endpoints and would send stored gateway credentials over that connection. Discovery beacons or setup codes could therefore steer the client onto a cleartext remote endpoint.

Impact

A user who followed a forged discovery result or scanned a crafted setup code could disclose stored gateway credentials to an attacker-controlled endpoint in plaintext. This was a transport-security bug in the Android gateway client.
