I am a bit late with this summary, but this week Apple released updates to all its operating systems and Safari. The Safari update, as usual, targets macOS prior to macOS 26. macOS updates covered the two older versions (14 and 15), while other operating system patches only covered the current 26 versions.
A total of 187 vulnerabilities are addressed in this update. Many cover multiple operating systems. Apple did not label any of the vulnerabilities as already being exploited.
Three vulnerabilities that caught my interest are CVE-2026-28849, CVE-2026-28900, and CVE-2026-28914. These issues appear to be the vulnerability described in https://m

Apple released updates for iOS/iPadOS, macOS, and Safari on Monday. There have been no updates for other Apple operating systems (visionOS, watchOS, tvOS). Usually, Apple updates all products at the same time.
Most of the vulnerabilities affect the web browser (WebKit, libxslt, WebRTC, and Web Extension). Only four of the vulnerabilities are not directly related to web content: Three Kernel issues and one vulnerability in the IOGPUFamily.
None of the vulnerabilities is labeled as "exploited".
