Description

OpenClaw versions prior to 2026.7.1 contain an authorization vulnerability allowing non-owner users to execute MCP configuration changes via /mcp set and /mcp unset commands. This flaw permits attackers to persist arbitrary stdio MCP commands that run with OpenClaw process privileges during configuration loading, impacting host confidentiality, integrity, and availability.

Technical Analysis

CVE-2026-100596 describes an authorization bypass vulnerability in OpenClaw before version 2026.7.1. Non-owner users can improperly execute MCP configuration changes using the /mcp set and /mcp unset commands. Exploitation allows attackers to persist arbitrary stdio MCP commands that execute with the privileges of the OpenClaw process when the configuration loads, leading to potential compromise of the host system's confidentiality, integrity, and availability.

Potential Impact

Successful exploitation enables attackers with limited privileges to execute arbitrary commands with OpenClaw process privileges. This can lead to full compromise of the host system's confidentiality, integrity, and availability, allowing unauthorized configuration changes and persistent malicious command execution.

Mitigation Recommendations

A fix is available in OpenClaw version 2026.7.1. Users should upgrade to version 2026.7.1 or later to remediate this vulnerability. No additional mitigation guidance is provided.
