Technical details
The vulnerability is a missing authorization check (CWE-862) in the Codex computer-use installation command. A non-owner channel sender with existing command access can invoke the installation command to install attacker-controlled plugins and trigger their associated MCP processes, which execute with OpenClaw user privileges. The attack requires network access and low privileges but no user interaction; patched version 2026.7.1 properly validates owner authorization before installation.
