Merely weeks after releasing out-of-band patches for iOS, iPadOS, macOS and watchOS, Apple has issued yet another security update for iPhone, iPad, and Apple Watch to fix a critical zero-day weakness that it says is being actively exploited in the wild.
Tracked as CVE-2021-1879, the vulnerability relates to a WebKit flaw that could enable adversaries to process maliciously crafted web content that may result in universal cross-site scripting attacks.
