Apple carries three high-severity macOS CVEs this period: a privilege escalation via logic flaw in macOS Tahoe (CVE-2026-20631, CVSS 8.8), a screen capture privacy bypass via improper temporary file handling affecting Sequoia and Tahoe (CVE-2026-20622, CVSS 7.5), and an integer overflow in string processing logic affecting Sequoia, Sonoma, and Tahoe (CVE-2026-20639, CVSS 7.5). None are actively exploited or CISA KEV-listed, and EPSS scores are uniformly low. Organizations should deploy macOS Tahoe 26.4, Sequoia 15.7.4 or 15.7.5 (depending on CVE), and Sonoma 14.8.5 via MDM within 30-day High-severity SLA, with priority for endpoints processing untrusted input or holding sensitive credentials.
