Background

OpenClaw is an npm package designed to facilitate media handling for Microsoft Teams, enabling seamless integration of attachments and content fetching from Microsoft Graph. It is crucial for ensuring that media is securely and efficiently managed within Teams applications. However, a vulnerability has been identified that compromises its security model, specifically related to the handling of fetch paths for media content.
