CVE-2025-24108 is a vulnerability identified in Apple macOS that stems from an access control issue related to sandbox restrictions. Specifically, the vulnerability allows an application running on the system to bypass certain sandbox constraints and gain access to protected user data that should otherwise be inaccessible. This flaw is categorized under CWE-862 (Missing Authorization), indicating that the system failed to properly enforce authorization checks before granting access to sensitive data. The vulnerability affects macOS versions prior to Sequoia 15.3, where the issue was resolved by implementing additional sandbox restrictions to prevent unauthorized data access. According to the CVSS 3.1 vector (AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N), exploitation requires local access (AV:L), has low attack complexity (AC:L), does not require privileges (PR:N), but does require user interaction (UI:R). The scope is unchanged (S:U), and the impact is high on confidentiality (C:H), with no impact on integrity (I:N) or availability (A:N). No known exploits have been reported in the wild, suggesting that active exploitation is not currently observed. However, the vulnerability poses a risk of unauthorized disclosure of sensitive user data if exploited. This vulnerability highlights the importance of robust sandboxing and access control mechanisms in protecting user privacy on macOS systems.

The primary impact of CVE-2025-24108 is the unauthorized disclosure of protected user data, which compromises confidentiality. Organizations relying on macOS systems, especially those handling sensitive or regulated data, face risks of data leaks that could lead to privacy violations, regulatory penalties, and reputational damage. Since exploitation requires local access and user interaction, the threat is more relevant in environments where users might inadvertently run malicious applications or where insider threats exist. The lack of impact on integrity and availability limits the scope to data confidentiality breaches only. However, the exposure of sensitive information can facilitate further attacks such as social engineering or targeted intrusions. Enterprises with macOS endpoints, including technology companies, creative industries, and government agencies, may be particularly vulnerable if systems are not updated. The absence of known exploits reduces immediate risk but does not eliminate the potential for future exploitation once the vulnerability details become widely known.

1. Update all macOS systems to version Sequoia 15.3 or later, where the vulnerability is patched. 2. Enforce strict application sandboxing policies and review app permissions regularly to minimize the risk of unauthorized data access. 3. Implement endpoint protection solutions that monitor and restrict the execution of untrusted or unsigned applications to reduce the chance of malicious apps running. 4. Educate users about the risks of running unknown or untrusted applications, emphasizing the need to avoid user interaction with suspicious prompts. 5. Employ least privilege principles for user accounts to limit the impact of local exploits. 6. Conduct regular audits of installed applications and their access rights to detect any anomalies. 7. Monitor system logs for unusual access patterns to protected data that might indicate exploitation attempts. 8. For organizations with sensitive data, consider additional data encryption at rest and in use to mitigate exposure even if sandboxing fails.
