It looks like Google Chrome for Android is facing a major security bug, and Google has already rolled the fix out. This browser exploit relates to the FileReader API and can allow a site to execute native code on your device.
Though Google has not released the details of this security flaw, the company says that the exploit already exists in the wild so people are potentially at risk. Therefore you should head to the Play Store and update Chrome as soon as you can.
This problem also exists in other versions of Chrome, like those on PC. You should check for updates across all of your devices, though your desktop browser should update automatically.
Google will release the full details of this exploit once most people have updated the browser but for now we’ll just have to settle for a quick fix. However, the issue may still exist in other Chromium-based browsers so beware. We’re just happy to see Google being so active in fixing security flaws.
