Chrome on Windows before version 98 may expose mouse movements

published 1 month ago
Summary

The Chromium‑based Chrome browser for Windows versions earlier than 98 does not correctly limit the Pointer Lock feature, which can let a website keep control of the mouse cursor. This could allow a malicious site to track user actions or interfere with other applications. Update Chrome to version 98 or later, or disable the Pointer Lock permission in the browser settings.

What to do
  • Update cleanstart chromium to version 98.0.4758.102-r0.
