Google Chrome’s security lead and engineering director, Justin Schuh, has warned that users of the most popular web browser should update “like right this minute.” Why the urgency? Simply put, there is a zero-day vulnerability for Chrome that the Google Threat Analysis Group has determined is being actively exploited in the wild. What does that all mean? Well, a vulnerability is just a bug or flaw in the code and while they all need to be fixed, not all of them either can be or are being exploited. A zero-day vulnerability is one that threat actors have managed to create an exploit for, a way of doing bad things to your device or data before the good guys even knew the vulnerability existed. In other words, they have zero days in which to issue a fix. The bad news for users of Google Chrome is that this particular zero-day vulnerability, CVE-2019-5786, is already being exploited by the bad guys. Which is why it’s so important to make sure your browser has been updated to the latest patched version that fixes the vulnerability.
