CVE-2025-24134 is a medium-severity information disclosure vulnerability identified in Apple macOS, specifically addressed in macOS Sequoia 15.3. The root cause lies in insufficient privacy controls that allow a malicious or compromised application to access sensitive user data without proper authorization. The vulnerability is categorized under CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor). According to the CVSS 3.1 vector (AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N), exploitation requires local access (i.e., the attacker must have the ability to run code on the target machine), with low attack complexity and no privileges required, but user interaction is necessary to trigger the data exposure. The scope is unchanged, meaning the vulnerability affects only the vulnerable component without impacting other system components. The vulnerability impacts confidentiality with a high impact rating, but does not affect integrity or availability. No public exploit code or reports of exploitation in the wild have been documented as of the publication date. The fix involves improved privacy controls implemented in macOS Sequoia 15.3, which restrict unauthorized app access to sensitive user data. This vulnerability highlights the importance of strict privacy enforcement in operating systems to prevent unauthorized data access by applications.

The primary impact of CVE-2025-24134 is the unauthorized disclosure of sensitive user data on affected macOS systems. This can lead to privacy violations, potential identity theft, or leakage of confidential information depending on the nature of the data accessed. For organizations, especially those handling sensitive or regulated data, this vulnerability could result in compliance violations, reputational damage, and potential legal consequences. Since exploitation requires local access and user interaction, the threat is more significant in environments where users may inadvertently run malicious applications or where endpoint security is weak. The vulnerability does not allow modification or disruption of system operations, limiting its impact to confidentiality breaches. However, the widespread use of macOS in enterprise, creative industries, and government sectors means that a successful exploit could have serious consequences for data privacy and security.

To mitigate CVE-2025-24134, organizations and users should promptly update all macOS devices to version Sequoia 15.3 or later, where the vulnerability is fixed. Beyond patching, organizations should enforce strict application control policies to limit the installation and execution of untrusted or unsigned applications. Employ endpoint protection solutions capable of detecting suspicious app behaviors that attempt to access sensitive data. User education is critical to reduce the risk of social engineering that could lead to the required user interaction for exploitation. Additionally, implementing least privilege principles and restricting local user permissions can reduce the attack surface. Regular audits of installed applications and privacy settings can help identify and remediate potential risks. Monitoring for unusual data access patterns on endpoints may provide early detection of exploitation attempts.
