CVE-2025-24281 is a vulnerability identified in Apple macOS that allows an application to access sensitive user data due to insufficient data protection mechanisms. The vulnerability is categorized under CWE-200, which relates to information exposure. Specifically, the flaw permits unauthorized disclosure of sensitive information without requiring elevated privileges (PR:N) but does require user interaction (UI:R), such as running or opening the malicious app. The attack vector is local (AV:L), meaning the attacker must have local access to the system. The vulnerability does not impact data integrity or system availability but compromises confidentiality (C:H, I:N, A:N). Apple addressed this issue in macOS Sequoia 15.4 by improving data protection controls to prevent unauthorized access. No public exploits have been reported, indicating the vulnerability is not yet actively exploited in the wild. The medium CVSS score of 5.5 reflects moderate risk, balancing the ease of exploitation with the impact on confidentiality. This vulnerability could be exploited by malicious apps or scripts that trick users into execution, potentially exposing personal or sensitive data stored on the device. Organizations relying on macOS devices should be aware of this vulnerability, especially in environments where sensitive data confidentiality is critical.

The primary impact of CVE-2025-24281 is unauthorized disclosure of sensitive user data on affected macOS systems. This can lead to privacy violations, leakage of confidential information, and potential downstream attacks such as identity theft or targeted phishing. Since the vulnerability does not affect integrity or availability, it does not allow data modification or system disruption. However, the exposure of sensitive data can undermine trust in affected systems and may lead to compliance issues for organizations handling regulated data. The requirement for local access and user interaction limits the scope somewhat, but in environments where users may run untrusted applications or where attackers have physical or remote local access, the risk is significant. Enterprises with macOS endpoints, especially in sectors like finance, healthcare, and government, could face data breaches if this vulnerability is exploited. The absence of known exploits in the wild currently reduces immediate risk but does not eliminate the potential for future attacks.

To mitigate CVE-2025-24281, organizations and users should promptly update all macOS devices to version Sequoia 15.4 or later, where the vulnerability is fixed. Beyond patching, organizations should enforce strict application control policies to prevent execution of untrusted or unsigned applications, reducing the risk of malicious apps exploiting this flaw. Employ endpoint detection and response (EDR) solutions capable of monitoring unusual local application behavior and data access patterns. Educate users about the risks of running unknown applications and the importance of verifying software sources. Implement least privilege principles to limit user permissions and reduce the impact of potential exploitation. Regularly audit sensitive data access logs to detect anomalous activity. For high-security environments, consider additional data encryption at rest and in use to minimize exposure even if unauthorized access occurs. Finally, maintain an up-to-date inventory of macOS devices to ensure timely patch deployment and vulnerability management.
