(NEXSTAR) — On Friday, Apple released a new update for its iOS software system that fixes a potentially serious security breach.

The new update impacts Webkit, a browser engine used in Safari.

According to Apple’s security website, Webkit is “processing maliciously crafted web content” that “may lead to universal cross site scripting.”

The issue “may have been actively exploited.”

Basically, the security threat “leaves your Apple device vulnerable to hacks regardless of whether you’re using Safari or other third-party browsers,” Mashable explains, hence why you should install the corrective update as soon as possible.

The update is available for the following devices:

To install it, navigate to Settings > General > Software Update, and click “Download and Install.”
