CVE-2025-43336 is a permissions-related vulnerability in Apple macOS that allows an application with root privileges to access private information that should otherwise be restricted. The root cause is a permissions misconfiguration or insufficient enforcement of access controls, classified under CWE-863 (Incorrect Authorization). This vulnerability does not require user interaction but does require the attacker to have root-level privileges on the system, which limits the attack vector to either local attackers or malicious software that has already escalated privileges. The issue was addressed by Apple through additional restrictions in macOS Sequoia 15.7.2, Sonoma 14.8.2, and Tahoe 26.1, which tighten the permissions model to prevent unauthorized access to sensitive data. The CVSS v3.1 base score is 4.4 (medium), reflecting the requirement for high privileges and the impact limited to confidentiality without affecting integrity or availability. No public exploits are known at this time, indicating the vulnerability is not yet actively exploited in the wild. However, the presence of root-level access as a prerequisite means that this vulnerability could be leveraged in post-exploitation scenarios to further compromise sensitive information on affected macOS systems.

The primary impact of CVE-2025-43336 is unauthorized disclosure of private information on macOS systems when an application with root privileges exploits the permissions issue. Although exploitation requires root access, which is already a high level of privilege, this vulnerability could allow malicious root-level applications or attackers who have escalated privileges to bypass intended access controls and extract sensitive data. This could lead to data breaches involving confidential user or system information. The vulnerability does not affect system integrity or availability, so it is less likely to cause system disruption or data modification. Organizations relying on macOS for critical operations, especially those handling sensitive data such as intellectual property, personal information, or classified information, may face increased risk if this vulnerability is exploited. The lack of known exploits reduces immediate risk but does not eliminate the threat, especially in targeted attacks or advanced persistent threat (APT) scenarios.

To mitigate CVE-2025-43336, organizations should prioritize updating all affected macOS systems to the patched versions: macOS Sequoia 15.7.2, macOS Sonoma 14.8.2, or macOS Tahoe 26.1. Beyond patching, organizations should implement strict controls on which applications are granted root privileges, employing the principle of least privilege to minimize the attack surface. Regularly audit and monitor applications running with elevated privileges to detect unauthorized or suspicious activity. Employ endpoint detection and response (EDR) solutions capable of identifying privilege escalation attempts and anomalous access to sensitive data. Additionally, enforce strong access controls and use macOS security features such as System Integrity Protection (SIP) and Mandatory Access Controls (MAC) to limit the capabilities of root-level processes where possible. Finally, maintain comprehensive logging and incident response plans to quickly address any exploitation attempts.
