CVE-2026-41295
OpenClaw < 2026.4.2 - Untrusted Workspace Channel Shadow Code Execution during Built-in Channel Setup
OpenClaw before 2026.4.2 contains an improper trust boundary vulnerability allowing untrusted workspace channel shadows to execute during built-in channel setup and login. Attackers can clone a workspace with a malicious plugin claiming a bundled channel id to achieve unintended in-process code execution before the plugin is explicitly trusted.

OpenClaw: Untrusted workspace channel shadows could execute during built-in channel setup
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.
