CVE-2025-24212 is a vulnerability in Apple’s iOS, iPadOS, and other related operating systems that allows an application to escape the sandbox environment. The sandbox is a critical security mechanism that restricts apps to their own isolated environment, preventing them from accessing unauthorized system resources or data from other apps. This vulnerability arises from insufficient validation or enforcement of sandbox boundaries, enabling a malicious or compromised app to break out and gain broader access to the system. The CVSS 3.1 base score is 6.3, reflecting a medium severity with a vector indicating local attack vector (AV:L), low attack complexity (AC:L), requiring low privileges (PR:L), no user interaction (UI:N), and a scope change (S:C) that affects confidentiality, integrity, and availability to a limited extent (C:L/I:L/A:L). The vulnerability affects multiple Apple platforms including iOS, iPadOS, macOS (Sequoia, Sonoma, Ventura), tvOS, visionOS, and watchOS. Apple has released patches in versions iOS 18.4, iPadOS 18.4 and 17.7.6, macOS 15.4, 14.7.5, 13.7.5, tvOS 18.4, visionOS 2.4, and watchOS 11.4 to address this issue by implementing improved sandbox boundary checks. No public exploits or active exploitation campaigns have been reported so far, but the potential for privilege escalation and unauthorized access makes this a significant concern for users and organizations relying on Apple devices.

If exploited, this vulnerability could allow a malicious app to escape its sandbox and gain unauthorized access to system resources or other apps’ data, undermining the core security model of Apple’s operating systems. This could lead to leakage of sensitive information, unauthorized modification of data, or disruption of system availability. For organizations, this means potential exposure of corporate data on employee devices, risk of lateral movement within managed device environments, and increased attack surface for advanced persistent threats. Although exploitation requires local access and some privilege, the lack of required user interaction lowers the barrier for automated or stealthy attacks once initial code execution is achieved. The scope change means the vulnerability affects system-wide security boundaries, increasing the severity beyond a single app compromise. Given the widespread use of Apple devices in enterprise, education, and government sectors, the impact could be broad if unpatched devices are targeted.

Organizations and users should prioritize updating all affected Apple devices to the patched OS versions: iOS 18.4 or later, iPadOS 18.4 or 17.7.6 or later, macOS Sequoia 15.4, Sonoma 14.7.5, Ventura 13.7.5 or later, tvOS 18.4, visionOS 2.4, and watchOS 11.4 or later. Beyond patching, organizations should enforce strict app vetting policies, limit installation of apps from untrusted sources, and use mobile device management (MDM) solutions to monitor and restrict app permissions. Employ runtime monitoring to detect anomalous app behavior indicative of sandbox escape attempts. Restrict local access to devices and enforce strong authentication to reduce the risk of initial compromise. Regularly audit device compliance and educate users about risks of installing unauthorized or suspicious apps. For high-security environments, consider additional endpoint protection solutions that can detect privilege escalation attempts.
