OpenClaw MCP Channel Permission Bypass

Publication date: 2026-09-26

Last updated on: 2026-09-26

Assigner: VulnCheck

Description
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.

Executive Summary

OpenClaw before version 2026.7.1 fails to enforce owner-only authorization for Claude Code permission prompts sent via the MCP channel bridge. An authorized non-owner channel sender with command access can approve or deny permission requests meant for the owner, allowing actions to proceed without owner consent.

Detection Guidance

To detect this vulnerability, check the installed version of the openclaw npm package. If it is below 2026.7.1, the system is vulnerable. Run: npm list openclaw. If the version is not shown or is older, update to 2026.7.1 or later immediately.

Impact Analysis

The impact depends on the pending action and requested host capabilities. A non-owner could approve unintended operations, potentially leading to unauthorized access, data manipulation, or system changes. The severity is high due to potential confidentiality, integrity, and availability impacts.

Compliance Impact

This vulnerability could potentially violate compliance requirements under GDPR and HIPAA by allowing unauthorized non-owner users to approve or deny permission requests intended for the owner. This bypasses owner consent for actions that may involve processing personal data or accessing sensitive systems, which could lead to unauthorized data access or modifications.

Mitigation Strategies

Upgrade OpenClaw to version 2026.7.1 or later to address the vulnerability. Before upgrading, avoid delivering permission prompts to channels with non-owner participants and cancel any unattended pending requests.
