CVE-2025-24119 is a vulnerability identified in Apple macOS that allows an application to execute arbitrary code outside its sandbox or with elevated privileges due to improper state management. This vulnerability is categorized under CWE-269, indicating an improper privilege management issue. The flaw enables an app, which already has some level of local privileges, to escalate those privileges further or escape sandbox restrictions, potentially leading to full system compromise. The CVSS v3.1 score is 7.8 (high), with vector AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H, meaning the attack requires local access and low complexity, with privileges already required but no user interaction. The impact on confidentiality, integrity, and availability is high, as arbitrary code execution with elevated privileges can allow attackers to access sensitive data, modify system configurations, or disrupt system operations. The vulnerability affects macOS versions prior to Sequoia 15.3, Ventura 13.7.7, and Sonoma 14.7.7, where Apple has implemented improved state management to fix the issue. There are no known exploits in the wild at the time of publication, but the potential for exploitation exists given the nature of the flaw. This vulnerability is particularly concerning for environments where macOS is used for sensitive or critical operations, as it could be leveraged by malicious insiders or attackers who gain local access to escalate privileges and bypass security controls.

For European organizations, the impact of CVE-2025-24119 can be significant, especially in sectors such as finance, government, healthcare, and technology where macOS devices are commonly used. Successful exploitation could lead to unauthorized access to sensitive information, disruption of critical services, and potential lateral movement within networks. The ability to execute arbitrary code with elevated privileges undermines the security model of macOS sandboxing, increasing the risk of persistent malware infections and data breaches. Organizations relying on macOS for endpoint security or operational technology could face operational downtime and reputational damage. The lack of user interaction requirement means that once local access is obtained, exploitation can be automated or triggered silently, increasing the threat level. Although no exploits are currently known in the wild, the high CVSS score and nature of the vulnerability suggest that attackers may develop exploits, making timely patching essential.

1. Immediate deployment of the official patches provided by Apple in macOS Sequoia 15.3, Ventura 13.7.7, and Sonoma 14.7.7 is critical to remediate this vulnerability. 2. Restrict local administrative privileges and limit the installation of untrusted applications to reduce the risk of local exploitation. 3. Implement strict application whitelisting and endpoint protection solutions that can detect anomalous behavior indicative of privilege escalation attempts. 4. Conduct regular audits of macOS systems to identify outdated versions and unauthorized software installations. 5. Employ network segmentation to limit the impact of a compromised macOS device on the broader organizational network. 6. Educate users about the risks of installing unverified software and the importance of reporting suspicious activity. 7. Monitor system logs and security events for signs of sandbox escapes or privilege escalation attempts. 8. Consider deploying macOS-specific security tools that enhance sandbox enforcement and privilege management.
