CVE-2025-24276 is an information disclosure vulnerability identified in Apple macOS operating systems, specifically affecting versions prior to macOS Sequoia 15.4, Sonoma 14.7.5, and Ventura 13.7.5. The flaw stems from vulnerable code that allowed a malicious application to access private user information without requiring elevated privileges (no privileges required) but necessitates user interaction to trigger the exploit. The vulnerability is classified under CWE-200, indicating exposure of sensitive information to unauthorized actors. The CVSS v3.1 base score is 5.5 (medium severity), with the vector AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N, meaning the attack requires local access (local vector), low attack complexity, no privileges, user interaction, unchanged scope, high confidentiality impact, and no impact on integrity or availability. The vulnerability was addressed by Apple through removal of the vulnerable code in the specified patched macOS versions. No public exploits have been reported, but the potential for malicious apps to harvest private data poses a privacy risk. This vulnerability primarily threatens confidentiality of sensitive information stored or processed on affected macOS systems.

The primary impact of CVE-2025-24276 is unauthorized disclosure of private information on affected macOS systems. This can lead to privacy violations, leakage of sensitive personal or corporate data, and potential subsequent attacks leveraging the disclosed information. Since the vulnerability requires local access and user interaction, the attack surface is limited to scenarios where an attacker can convince or trick a user into running a malicious app locally. However, given the widespread use of macOS in enterprise, creative social engineering or supply chain attacks could enable exploitation. The lack of impact on integrity and availability reduces the risk of system compromise or denial of service, but the confidentiality breach alone can have serious consequences for individuals and organizations, including regulatory compliance violations and reputational damage.

Organizations and users should promptly update affected macOS systems to versions Sequoia 15.4, Sonoma 14.7.5, or Ventura 13.7.5 or later, where the vulnerable code has been removed. Restricting installation of applications to trusted sources, such as the Apple App Store or verified developers, can reduce the risk of malicious apps being executed. Employing endpoint protection solutions that monitor for suspicious local app behavior may help detect exploitation attempts. User awareness training to recognize and avoid executing untrusted applications or links can mitigate the required user interaction vector. Additionally, implementing strict application whitelisting and leveraging macOS security features like Gatekeeper and System Integrity Protection (SIP) can further reduce exposure. Regular auditing of installed applications and monitoring for anomalous access to private information is recommended.
