Background

OpenClaw is an open-source package designed for natural language processing and command execution. It allows users to interact with applications using natural language commands. However, a critical vulnerability has been identified that permits unauthorized senders to bypass sender authorization checks, potentially leading to unauthorized command execution and data exposure.

Vulnerability Detail

The vulnerability arises from a lack of sender authorization checks in two specific command paths: stop-like natural-language abort triggers and the '/models' command output. This oversight allows unauthorized users to disrupt active sessions and access model and authentication metadata that should be restricted. The absence of proper authorization mechanisms poses a significant risk to the integrity and confidentiality of the application.
