CVE-2026-35674 Details
Description
OpenClaw before 2026.5.18 contains a scope bypass vulnerability in the Gateway chat.send route that allows scoped clients to execute privileged commands. Attackers with operator.write scope can deliver commands through inherited external routes to bypass operator.approvals and operator.admin scope requirements, enabling unauthorized plugin, config, MCP, allowlist, and ACP mutations.
A scope bypass vulnerability has been identified in OpenClaw versions prior to 2026.5.18. This vulnerability exists in the Gateway 'chat.send' route, allowing scoped clients to execute privileged commands. Attackers with 'operator.write' scope can send commands through inherited external routes, bypassing the 'operator.approvals' and 'operator.admin' scope requirements. This exploitation enables unauthorized modifications to plugins, configurations, MCP, allowlists, and ACP.
Users are advised to upgrade to OpenClaw version 2026.5.18 or later. Before upgrading, it is recommended to avoid granting 'operator.write' tokens to clients that can send commands into sessions with external routes, unless those clients are trusted with administrative command effects.
