CVE-2025-43407 is a vulnerability identified in Apple’s iOS and iPadOS platforms, as well as related operating systems including macOS Sequoia, Sonoma, Tahoe, tvOS, and visionOS. The core issue stems from insufficient enforcement of application entitlements, which are security controls that restrict app capabilities and access to system resources. Due to this flaw, a malicious or compromised app can escape its sandbox—a security mechanism designed to isolate apps from each other and the underlying system—and gain unauthorized access to sensitive system components and data. The vulnerability is classified under CWE-284, indicating improper access control. The CVSS v3.1 base score is 7.8 (high), with vector AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H, meaning the attack requires local access and user interaction but no privileges, and can lead to high impact on confidentiality, integrity, and availability. Apple addressed this issue by improving entitlement enforcement in OS updates 26.1 for iOS, iPadOS, and related platforms. Although no active exploits have been reported, the potential for privilege escalation and sandbox escape makes this a critical concern for users and organizations relying on Apple devices. The vulnerability’s exploitation could allow attackers to execute arbitrary code with elevated privileges, access private user data, or disrupt system operations.

The impact of CVE-2025-43407 is significant for organizations worldwide that deploy Apple devices, including iPhones, iPads, Macs, Apple TVs, and visionOS devices. Successful exploitation allows a malicious app to break out of its sandbox, bypassing critical security boundaries designed to protect user data and system integrity. This can lead to unauthorized access to sensitive information, installation of persistent malware, and potential disruption of device functionality. For enterprises, this could mean data breaches, loss of intellectual property, and compromised device management. The vulnerability affects confidentiality, integrity, and availability, posing risks to both personal and corporate environments. Given the widespread use of Apple devices in sectors such as finance, healthcare, government, and technology, the threat could have broad implications. Although exploitation requires local access and user interaction, social engineering or delivery via malicious apps could facilitate attacks. The absence of known exploits in the wild currently reduces immediate risk but does not diminish the urgency of patching, as threat actors may develop exploits once the vulnerability details are public.

To mitigate CVE-2025-43407, organizations and users should promptly update all affected Apple devices to the latest OS versions where the vulnerability is patched (iOS and iPadOS 26.1, macOS Sequoia 15.7.2, Sonoma 14.8.2, Tahoe 26.1, tvOS 26.1, visionOS 26.1). Beyond patching, organizations should enforce strict app installation policies, allowing only apps from trusted sources such as the Apple App Store with verified developer credentials. Employ Mobile Device Management (MDM) solutions to monitor and restrict app permissions and entitlements. Educate users about the risks of installing untrusted applications and the importance of user interaction in exploitation scenarios. Implement runtime protection and behavior monitoring on devices to detect anomalous app activities indicative of sandbox escape attempts. Regularly audit installed apps and system logs for suspicious behavior. For high-security environments, consider additional endpoint protection solutions tailored for Apple platforms that can detect privilege escalation attempts. Finally, maintain an incident response plan that includes Apple device compromise scenarios to ensure rapid containment and remediation if exploitation occurs.
