CVE-2025-31249 is a logic vulnerability identified in Apple macOS that allows an application to bypass intended access controls and retrieve sensitive user data. The root cause is a flaw in the authorization logic, categorized under CWE-285 (Improper Authorization), where the system fails to enforce adequate permission checks before granting access to protected data. This vulnerability affects macOS versions prior to the release of macOS Sequoia 15.5, which contains the fix through improved validation mechanisms. The CVSS 3.1 base score of 7.1 reflects a high severity, with an attack vector of network (AV:N), low attack complexity (AC:L), requiring privileges (PR:L) but no user interaction (UI:N), and impacting confidentiality heavily (C:H), with limited impact on integrity (I:L) and no impact on availability (A:N). Exploiting this flaw enables an attacker with limited privileges on the system to access sensitive information that should otherwise be protected, potentially including personal user data, credentials, or other confidential files. Although no active exploits have been reported, the vulnerability's characteristics make it a viable target for attackers seeking data exfiltration. The lack of user interaction requirement increases the risk of automated or remote exploitation. This vulnerability underscores the importance of robust access control logic in operating systems to prevent privilege escalation and unauthorized data access.

For European organizations, the impact of CVE-2025-31249 could be significant, especially for those relying on macOS devices for daily operations, including government agencies, financial institutions, and enterprises handling sensitive personal or corporate data. Unauthorized access to sensitive user data could lead to data breaches, loss of intellectual property, regulatory non-compliance (e.g., GDPR violations), and reputational damage. The confidentiality breach could expose personal identifiable information (PII), trade secrets, or credentials that attackers might leverage for further attacks. Given the high adoption rate of Apple devices in sectors such as creative industries, technology firms, and public administration in Europe, the vulnerability presents a tangible risk. Although the vulnerability does not affect system availability or integrity directly, the confidentiality compromise alone can have cascading effects on organizational security posture and trustworthiness. The absence of known exploits in the wild currently provides a window for proactive mitigation before widespread exploitation occurs.

1. Immediate upgrade to macOS Sequoia 15.5 or later, where the vulnerability is patched, is the most effective mitigation. 2. Implement strict application whitelisting and permission management to limit app capabilities and reduce the attack surface. 3. Employ endpoint detection and response (EDR) solutions capable of monitoring unusual access patterns or privilege escalations on macOS devices. 4. Conduct regular audits of installed applications and their permissions to identify and remove potentially risky or unauthorized software. 5. Educate users and IT staff about the risks of installing untrusted applications and the importance of timely updates. 6. For organizations with sensitive data, consider additional encryption of data at rest and in transit to mitigate exposure if unauthorized access occurs. 7. Monitor security advisories from Apple and threat intelligence feeds for any emerging exploit activity related to this CVE. 8. Integrate vulnerability management processes to ensure rapid deployment of patches across all macOS endpoints in the environment.
