Is UpStudy - Best AI Tutor safe?

Low risk

UpStudy lets any website open an attacker-chosen WebSocket and make authenticated calls to its backend using your saved session.

UpStudy injects a message listener into every website that checks only that a message came from the page's own origin, not who sent it, so any site can send it commands. Those commands reach the extension's background service worker, which can open a WebSocket to an address the website supplies and can also submit form data to UpStudy's own backend while automatically attaching your stored session ID from local storage. This means a malicious or compromised webpage can trigger authenticated requests to UpStudy's servers on your behalf, without any action from you beyond visiting the page.
