CVE-2025-30429 is a vulnerability identified in Apple tvOS and several other Apple operating systems, including visionOS, macOS Ventura, macOS Sequoia, macOS Sonoma, iPadOS, and iOS. The root cause is a path handling issue that allows an application to bypass the sandbox restrictions imposed by the operating system. Sandboxing is a critical security mechanism that isolates applications to prevent them from accessing unauthorized system resources or user data. The vulnerability arises from insufficient validation of file system paths, which can be exploited by a malicious or compromised app to escape its sandbox environment. This escape could enable the app to access or modify data and system components beyond its intended scope, potentially leading to confidentiality breaches, integrity violations, or availability disruptions. The CVSS v3.1 score of 6.3 reflects a medium severity level, with the vector indicating that the attack requires local access (AV:L), low attack complexity (AC:L), privileges (PR:L), no user interaction (UI:N), and that the impact affects confidentiality, integrity, and availability to a limited extent (C:L/I:L/A:L). The vulnerability has been addressed in Apple’s security updates released in March 2025, specifically in tvOS 18.4, macOS Ventura 13.7.5, and other listed OS versions. No known exploits have been reported in the wild, but the potential for sandbox escape makes this a significant risk, especially in environments where apps are installed from less trusted sources or where local access controls are weak.

For European organizations, this vulnerability poses a risk primarily to environments using Apple tvOS devices and other affected Apple platforms. The ability for an app to escape its sandbox could lead to unauthorized access to sensitive information, modification of critical system files, or disruption of services. This is particularly concerning for sectors such as finance, healthcare, government, and critical infrastructure where Apple devices are used for media, communication, or operational purposes. The impact includes potential data breaches, loss of data integrity, and service interruptions. Since the attack requires local access and some privileges, insider threats or compromised user accounts could exploit this vulnerability. The lack of user interaction requirement increases the risk of automated or stealthy exploitation once local access is obtained. Organizations relying on Apple ecosystems for secure application deployment must consider this vulnerability a serious risk to their security posture.

1. Apply the security updates released by Apple immediately, specifically tvOS 18.4, macOS Ventura 13.7.5, and corresponding versions for other affected OSes. 2. Restrict app installations to trusted sources such as the official Apple App Store and enforce strict app vetting policies. 3. Implement robust access controls to limit local access to devices, including strong authentication and role-based access controls. 4. Monitor device behavior for anomalies that may indicate sandbox escape attempts, such as unexpected file system access or privilege escalations. 5. Use Mobile Device Management (MDM) solutions to enforce security policies and ensure timely patch deployment across all Apple devices. 6. Educate users about the risks of installing untrusted applications and the importance of reporting suspicious device behavior. 7. Conduct regular security audits and penetration testing focused on Apple device environments to detect potential exploitation attempts.
