CVE-2025-24276 is a vulnerability identified in Apple macOS that allows a malicious application to access private information on the affected system. The vulnerability stems from the presence of vulnerable code that improperly exposes sensitive data, categorized under CWE-200 (Exposure of Sensitive Information). The issue was addressed by Apple through the removal of this vulnerable code in macOS Ventura 13.7.5, macOS Sequoia 15.4, and macOS Sonoma 14.7.5. The CVSS 3.1 base score is 5.5, indicating a medium severity level. The vector string (AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N) reveals that exploitation requires local access (AV:L), low attack complexity (AC:L), no privileges (PR:N), and user interaction (UI:R). The scope remains unchanged (S:U), and the impact is high on confidentiality (C:H), with no impact on integrity (I:N) or availability (A:N). This means a malicious app, once executed by the user, can read sensitive information without altering system state or availability. No known exploits are currently reported in the wild, but the vulnerability poses a risk for data leakage if exploited. The affected versions are unspecified but are understood to be all versions prior to the patched releases. The vulnerability is particularly relevant for environments where macOS is widely used and where sensitive data confidentiality is critical.

For European organizations, the primary impact of CVE-2025-24276 is the potential unauthorized disclosure of sensitive information stored on macOS devices. This could include personal data, corporate intellectual property, or other confidential information. Since exploitation requires local access and user interaction, the threat is more pronounced in environments where users may install untrusted applications or where endpoint security controls are lax. The confidentiality breach could lead to regulatory compliance issues under GDPR, reputational damage, and potential financial losses. Organizations with remote or hybrid workforces using macOS devices are at increased risk if endpoint protections are insufficient. The lack of impact on integrity and availability reduces the risk of system disruption but does not diminish the importance of protecting sensitive data. The absence of known exploits in the wild provides a window for proactive mitigation before widespread exploitation occurs.

European organizations should immediately verify the macOS versions deployed across their endpoints and prioritize upgrading to macOS Ventura 13.7.5, Sequoia 15.4, or Sonoma 14.7.5 where applicable. Restricting the installation of applications to those from trusted sources, such as the Apple App Store or enterprise-approved software repositories, will reduce the risk of malicious app execution. Implementing endpoint detection and response (EDR) solutions capable of monitoring for suspicious local application behavior can provide early warning of exploitation attempts. User awareness training should emphasize the risks of installing untrusted applications and the importance of prompt software updates. Additionally, enforcing least privilege principles and using macOS security features like System Integrity Protection (SIP) and Gatekeeper can help mitigate exploitation. Regular audits of installed applications and system configurations will help identify potential exposure. Organizations should also monitor threat intelligence feeds for any emerging exploit activity related to this CVE.
