Summary

Before OpenClaw 2026.4.2, built-in channel setup and login could resolve an untrusted workspace channel shadow before the plugin was explicitly trusted. A malicious workspace plugin that claimed a bundled channel id could execute during channel setup even while still disabled.

Impact

A cloned workspace could turn channel setup for a built-in channel into unintended in-process code execution from an untrusted workspace plugin. This bypassed the intended workspace-plugin trust boundary during setup and login.
