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
