CVE-2024-44152 is a privacy vulnerability identified in Apple macOS, fixed in the recently released macOS Sequoia 15. The issue stems from inadequate redaction of private data in system log entries, allowing applications to access sensitive user information that should otherwise be protected. The vulnerability is classified under CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor). According to the CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N), the flaw is remotely exploitable over the network without requiring any privileges or user interaction, and it impacts confidentiality with a high severity score of 7.5. The vulnerability does not affect data integrity or system availability. Although no exploits have been reported in the wild, the potential for unauthorized data disclosure is significant. The root cause is insufficient private data redaction in logs, which could leak sensitive user information to any app capable of reading these logs. Apple’s fix involves enhancing the redaction mechanisms to prevent sensitive data exposure. This vulnerability primarily affects macOS versions prior to Sequoia 15, and organizations using these versions should consider immediate patching to mitigate risk.

The primary impact of CVE-2024-44152 is the unauthorized disclosure of sensitive user data, which can lead to privacy breaches and potential downstream attacks such as identity theft, targeted phishing, or corporate espionage. Since the vulnerability allows remote exploitation without authentication or user interaction, it poses a significant risk to confidentiality on affected macOS systems. Organizations relying on macOS for critical operations, especially those handling sensitive or regulated data, may face compliance violations and reputational damage if exploited. Although integrity and availability are not impacted, the exposure of sensitive information can undermine trust and security posture. The lack of known exploits in the wild reduces immediate risk but does not eliminate the threat, as attackers may develop exploits given the public disclosure. The vulnerability’s network attack vector and low complexity make it attractive for attackers targeting macOS environments globally.

The primary mitigation is to upgrade all affected macOS systems to macOS Sequoia 15, where the issue is fully addressed. Until patching is possible, organizations should restrict application permissions to limit access to system logs and sensitive data. Employing endpoint detection and response (EDR) solutions to monitor unusual access patterns to logs can help detect potential exploitation attempts. Administrators should audit and harden logging configurations to minimize sensitive data exposure. Network-level controls such as firewall rules can reduce exposure by limiting unnecessary inbound connections to macOS devices. Additionally, educating users about the risks and encouraging minimal installation of untrusted applications can reduce the attack surface. Regularly reviewing Apple security advisories and applying updates promptly is critical to maintaining protection against this and future vulnerabilities.
