Background
OpenClaw is an open-source automation tool that allows users to configure hooks for automated agent runs. It is designed to streamline processes by enabling users to trigger actions based on specific events. However, the tool has a vulnerability that can lead to unauthorized access to owner-scoped tools when hooks are enabled.
Vulnerability Detail
The vulnerability arises from the OpenClaw hook ingress mechanism, which can initiate automated agent runs using a configured hook token. In certain affected versions, a hook-triggered run could select a bundled CLI backend that inadvertently receives owner-scoped MCP loopback authority, rather than the appropriate scope for hook ingress. This flaw allows a caller with the hook token to access or invoke MCP tools that should be restricted to owner-only use. The practical implications of this vulnerability depend on the specific MCP tools available, with reported instances using persistent cron state as an example of an owner-only action that could be exploited.
