Is Desktop companion app for Dynamics 365 Contact Center safe?

Low risk

The extension relays postMessage payloads from any HTTPS page to the com.dynamics.vca native app without validating the sender's origin.

The content script listens for window.postMessage events on all HTTPS pages and forwards any message with direction set to MESSAGE_TO_VCA directly to the extension's service worker, which passes it to a native host application via chrome.runtime.connectNative. Because the handler checks only the message direction field and not event.origin, any web page running over HTTPS can send commands to the native Dynamics 365 Contact Center desktop companion without restriction.
