CVE-2025-24142 is a privacy vulnerability identified in Apple macOS operating systems that stems from inadequate redaction of sensitive user data in system log entries. This flaw allows a local application to access sensitive information that should have been protected or obscured within logs. The vulnerability affects macOS versions prior to Sequoia 15.5, Sonoma 14.7.6, and Ventura 13.7.6, where Apple has implemented improved private data redaction mechanisms to address the issue. The vulnerability is categorized under CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor). According to the CVSS v3.1 vector (AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N), exploitation requires local access with low attack complexity, no privileges, and user interaction, but it only impacts confidentiality without affecting integrity or availability. No known exploits have been reported in the wild, indicating limited active exploitation at this time. The root cause is insufficient sanitization or masking of sensitive data in logs, which can be read by malicious or compromised applications with local user access. This vulnerability underscores the risks associated with improper handling of sensitive information in system diagnostics and logging frameworks, which can lead to privacy breaches if exploited.

The primary impact of CVE-2025-24142 is the unauthorized disclosure of sensitive user data through improperly redacted log entries. For organizations, this can lead to privacy violations, potential leakage of personally identifiable information (PII), credentials, or other confidential data that may be stored or referenced in logs. Such exposure can facilitate further attacks such as social engineering, credential theft, or targeted exploitation if attackers gain local access. Although the vulnerability does not allow privilege escalation or system compromise directly, the confidentiality breach can undermine trust and compliance with data protection regulations like GDPR or HIPAA. Organizations with macOS endpoints, especially those handling sensitive data or operating in regulated industries, face increased risk if patches are not applied. The requirement for user interaction and local access limits remote exploitation but does not eliminate insider threats or risks from malware running with user privileges. Overall, the vulnerability can degrade the security posture by exposing sensitive information that should remain confidential.

To mitigate CVE-2025-24142, organizations should prioritize deploying the security updates provided by Apple in macOS Sequoia 15.5, Sonoma 14.7.6, and Ventura 13.7.6 or later versions that include improved private data redaction. Beyond patching, organizations should audit and restrict local application permissions to minimize the risk of unauthorized apps accessing sensitive logs. Implement strict endpoint security controls such as application whitelisting and user privilege management to reduce the likelihood of malicious or untrusted applications running with user-level access. Regularly review logging configurations to ensure sensitive data is not unnecessarily logged or exposed. Employ monitoring solutions to detect unusual local access patterns or attempts to read system logs. Educate users about the risks of running untrusted software and the importance of applying updates promptly. For environments with high privacy requirements, consider additional data encryption or log access controls to further protect sensitive information. Finally, maintain an incident response plan that includes steps to investigate potential data exposure through logs.
