CVE-2025-43311

Vulnerability

Overview

CVE-2025-43311 is a logic flaw in macOS that permits an app to bypass privacy controls and access protected user data. The issue was addressed with additional entitlement checks, implying that the missing verification of application rights allowed unauthorized data access. Apple has classified this as a medium-severity issue with a CVSS v3 score of 5.1 [1].

Attack

Vector

The vulnerability can be exploited locally by a malicious or compromised application. No special network access is required, as an attacker would need to convince a user to run a crafted app on an affected Mac system. The lack of proper entitlement validation during certain operations enabled the app to circumvent user privacy preferences [1][4].

Impact

Successful exploitation grants the attacker access to protected user data, which could include documents, contacts, or other sensitive information normally sandboxed by macOS privacy controls. The impact affects all recent Mac hardware, including Intel and Apple silicon models [1][2].

Mitigation

Apple has released security updates for macOS Sequoia 15.7, macOS Sonoma 14.8, and macOS Tahoe 26 on September 15, 2025. Users are advised to install the appropriate update for their operating system version to remediate the vulnerability [1][3][4].
