Who should care

macOS administrators and users of affected systems should be aware of this vulnerability and take steps to patch vulnerable systems. Additionally, security teams and operators responsible for macOS systems should review and apply patches to prevent potential data exposure. Organizations should prioritize patching vulnerable systems to prevent potential data exposure and review compensating controls for exposed systems while remediation is scheduled and

Why it matters

CVE-2026-43741 is a logic issue in macOS that may allow an app to access protected user data. macOS administrators should prioritize patching vulnerable systems to prevent potential data exposure.

• App access to protected user data may occur if vulnerable systems are not patched
• macOS administrators must verify and apply patches to prevent potential data exposure

Technical summary

A logic issue was addressed with improved state management in macOS Golden Gate 27, macOS Sequoia 15.8, and macOS Tahoe 26.7. This issue may allow an app to access protected user data. The vulnerability is related to state management and could be exploited by a malicious app to gain unauthorized access to sensitive data. Apple has addressed the issue through patches for affected systems, and users should ensure their systems are updated to prevent exploitation.
