CVE-2025-30443 is a privacy vulnerability identified in Apple macOS that allows a malicious or compromised application to access user-sensitive data improperly. The root cause is a flaw in the system code that failed to adequately restrict access controls, leading to unauthorized data exposure (classified under CWE-200: Exposure of Sensitive Information to an Unauthorized Actor). This vulnerability affects multiple macOS versions prior to the patched releases: Ventura 13.7.5, Sequoia 15.4, and Sonoma 14.7.5. The vulnerability requires local access (AV:L) and user interaction (UI:R), but no privileges (PR:N) or authentication are necessary, making it exploitable by any app the user runs that can trigger the flaw. The CVSS v3.1 base score is 5.5, reflecting medium severity, primarily due to the high confidentiality impact (C:H) while integrity and availability remain unaffected (I:N, A:N). The vulnerability was addressed by Apple through removal of the vulnerable code, indicating a code-level fix rather than a configuration or policy change. No public exploits or active exploitation have been reported to date. The vulnerability poses a risk of sensitive data leakage, which could include personal information, credentials, or other confidential data stored or accessible on the affected macOS systems. Since macOS is widely used in enterprise environments, especially in creative, financial, and technology sectors, the exposure could have significant privacy implications if exploited.

For European organizations, the primary impact of CVE-2025-30443 is the potential unauthorized disclosure of sensitive user data, which can lead to privacy breaches, regulatory non-compliance (e.g., GDPR), and reputational damage. Organizations handling personal data, intellectual property, or confidential business information on macOS devices are at risk. The vulnerability could be exploited by malicious insiders or malware that convinces users to run a crafted app, leading to data leakage without altering system integrity or availability. This risk is particularly relevant for sectors with stringent data protection requirements such as finance, healthcare, legal, and government agencies. The medium severity and requirement for user interaction reduce the likelihood of widespread automated exploitation but do not eliminate targeted attacks. Additionally, the lack of known exploits in the wild provides a window for organizations to patch and mitigate before active exploitation occurs.

1. Immediately apply the security updates provided by Apple: macOS Ventura 13.7.5, Sequoia 15.4, and Sonoma 14.7.5 or later versions that include the fix. 2. Enforce strict application control policies using Apple’s built-in tools such as Gatekeeper and System Integrity Protection to limit the execution of untrusted or unsigned applications. 3. Educate users to avoid running unknown or suspicious applications, emphasizing the risk of user interaction in exploitation. 4. Utilize endpoint detection and response (EDR) solutions capable of monitoring application behavior for suspicious access to sensitive data. 5. Regularly audit and restrict app permissions to the minimum necessary, especially for apps that handle sensitive information. 6. Implement network segmentation and data loss prevention (DLP) controls to limit the impact of any data leakage. 7. Maintain an up-to-date asset inventory to identify all macOS devices and ensure timely patch deployment. 8. Monitor threat intelligence sources for any emerging exploit reports related to this CVE to adjust defenses accordingly.
