CVE-2026-100596 PUBLISHED

OpenClaw before 2026.7.1 Authorization Bypass via MCP Configuration

Assigner: VulnCheck
Reserved: 26.09.2026 Published: 26.09.2026 Updated: 26.09.2026

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.
