Background

OpenClaw is an npm package designed to facilitate interactions with Discord's API, enabling developers to create and manage Discord bots and applications. It provides various functionalities, including event management, media handling, and user interactions. However, a recent vulnerability has been identified that allows Discord event cover images to bypass the expected media normalization process, potentially leading to unauthorized media access within the application.

Vulnerability Detail

The vulnerability arises from the failure of Discord event cover images to undergo proper sandbox media normalization. This oversight allows host-local media references to be processed in a manner that could compromise the integrity of channel actions, which expect normalized media. The technical fix involves including the 'eventCreate.image' parameter in the sandbox media normalization process, thus preventing unauthorized access to local media references.
