# CVE-2026-100596

> 8.7 HIGH · 🧪 PoC

## Beschreibung

OpenClaw versions before 2026.7.1 fail to properly authorize non-owner users executing MCP configuration changes through /mcp set and /mcp unset commands. Attackers can persist arbitrary stdio MCP commands that execute with OpenClaw process privileges when configuration loads, compromising host confidentiality, integrity, and availability.
