CVE-2026-41295
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.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.13%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
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.
