OpenClaw lets non-owner approve permission requests

CVE-2026-100585 · published 18 days ago
Summary

The OpenClaw library (versions before 2026.7.1) does not correctly limit who can approve certain permission prompts. A user who can send commands through the MCP channel can approve or reject requests that should only be handled by the owner, potentially allowing actions without the owner’s consent. Upgrade to version 2026.7.1 or later to restore proper owner‑only checks.

What to do
  • Update openclaw openclaw to version 2026.7.1 or later.

Original advisory text
OpenClaw before 2026.7.1 Authentication Bypass via MCP Channel
OpenClaw (npm package `openclaw`) before 2026.7.1 fails to enforce the owner-only authorization requirement for Claude Code permission prompts delivered through the MCP channel bridge. An authorized non-owner channel sender with channel command access can approve or deny a pending permission request intended for the owner, causing the requested action to proceed without owner consent. The practical impact depends on the pending action and the host capabilities requested by the Claude Code run. The issue is fixed in version 2026.7.1.
