26
FAUCET Score

CVE-2026-28817 is a high-severity race condition (CWE-362) affecting Apple macOS, which could allow a sandboxed process to circumvent security restrictions due to improved state handling. This vulnerability is addressed in macOS Sequoia 15.7.5, macOS Sonoma 14.8.5, and macOS Tahoe 26.4. With a CVSS v3.1 score of 8.1 (High), exploitation requires local access and has high attack complexity, but no user interaction or privileges are needed, potentially leading to significant impact on confidentiality, integrity, and availability.
