JxBrowser 7.43.8

Chromium 139.0.7258.67

We upgraded Chromium to a newer version, which introduces 12 security fixes. Among them:

• CVE-2025-8576: Use after free in Extensions
• CVE-2025-8577: Inappropriate implementation in Picture In Picture
• CVE-2025-8578: Use after free in Cast

You can read more about it in the Chromium blog post.

End of support for macOS 11

Chromium 139 no longer supports macOS 11, so we also dropped support for this version in JxBrowser 7.43.8. The latest JxBrowser version that supports macOS 11 is 7.43.7.

Quality enhancement & changed behavior

Fixed the issue with selecting media device from JavaScript. When the web page calls getUserMedia({ audio: true }), the SelectMediaDeviceCallback is called and Chromium uses the device returned from the Java side. But when the web page calls getUserMedia({ audio: {deviceId: 'foo-bar'} }), the result of the callback is ignored.

To fix the bug, we modified the behavior of the select(MediaDevice) response. It now selects only the given media device and only this device will be visible to JavaScript.
