CVE-2026-100585
OpenClaw before 2026.7.1 Authentication Bypass via MCP Channel
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.
