CVE-2025-43358 is a vulnerability identified in Apple’s macOS and related operating systems, including iOS and iPadOS, where a permissions issue allows a shortcut to bypass sandbox restrictions. Sandboxing is a critical security mechanism that isolates applications and limits their access to system resources and user data. This vulnerability arises from insufficient enforcement of sandbox policies, permitting a crafted shortcut to escape these restrictions and potentially execute unauthorized actions with elevated privileges. The flaw affects multiple Apple OS versions, including macOS Sonoma 14.8, macOS Sequoia 15.7, iOS 26, iPadOS 26, iOS 18.7, and iPadOS 18.7. The CVSS 3.1 base score of 8.8 reflects a high-severity issue with local attack vector (AV:L), low attack complexity (AC:L), requiring low privileges (PR:L), no user interaction (UI:N), and scope change (S:C), resulting in high confidentiality, integrity, and availability impacts (C:H/I:H/A:H). This means an attacker with limited local access can exploit the vulnerability without user interaction to gain control beyond the original sandbox constraints, potentially accessing sensitive data, modifying system files, or disrupting system availability. Although no exploits have been reported in the wild yet, the vulnerability’s nature and impact make it a critical concern for organizations relying on Apple platforms. The underlying CWE-862 (Missing Authorization) indicates that the system failed to properly authorize actions within the sandbox environment. Apple has addressed this issue by enhancing sandbox restrictions in the patched OS versions. However, the lack of detailed patch links suggests organizations should rely on official Apple updates and advisories to remediate the vulnerability.

The impact of CVE-2025-43358 is significant for organizations using affected Apple operating systems. Successful exploitation allows an attacker with limited privileges to bypass sandbox restrictions, leading to unauthorized access to sensitive data, modification of system or application files, and potential disruption of system availability. This can result in data breaches, loss of data integrity, and denial of service conditions. Since the vulnerability requires no user interaction and has a low complexity of exploitation, it poses a high risk in environments where local access is possible, such as shared workstations, managed devices, or compromised user accounts. The scope change indicates that the attacker can affect resources beyond the initially compromised sandbox, potentially escalating privileges and moving laterally within the system. This elevates the threat to critical infrastructure, enterprises with sensitive intellectual property, and organizations handling regulated data. The absence of known exploits in the wild currently reduces immediate risk but does not diminish the urgency for remediation, as threat actors may develop exploits rapidly once the vulnerability is public. The widespread use of Apple devices in corporate, government, and consumer sectors globally means the potential impact is broad and could affect diverse industries.

To mitigate CVE-2025-43358, organizations should immediately apply the security updates released by Apple for macOS Sonoma 14.8, macOS Sequoia 15.7, iOS 26, iPadOS 26, iOS 18.7, and iPadOS 18.7. Beyond patching, organizations should implement the following specific measures: 1) Restrict the creation and execution of shortcuts to trusted users and administrators only, minimizing the risk of malicious shortcut deployment. 2) Monitor and audit shortcut activities and sandbox escape attempts using endpoint detection and response (EDR) tools capable of detecting anomalous process behaviors related to shortcuts. 3) Enforce strict access controls and least privilege principles on Apple devices, limiting local user privileges to reduce exploitation opportunities. 4) Educate users about the risks of executing untrusted shortcuts and encourage reporting of suspicious behavior. 5) Utilize mobile device management (MDM) solutions to enforce security policies and automate patch deployment across Apple device fleets. 6) Consider network segmentation and application whitelisting to contain potential lateral movement if exploitation occurs. These targeted actions complement patching and reduce the attack surface related to shortcut-based sandbox escapes.
