CVE-2025-43358 is a vulnerability identified in Apple iOS and iPadOS that involves a permissions issue allowing 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 authorization checks within the shortcut execution environment, enabling a shortcut to perform actions beyond its intended sandbox boundaries. The flaw affects iOS and iPadOS versions prior to 18.7 and macOS versions prior to Sequoia 15.7, Sonoma 14.8, and Tahoe 26. The vulnerability is classified under CWE-862, indicating missing authorization controls. The CVSS v3.1 base score of 8.8 reflects high severity, with attack vector local (AV:L), low attack complexity (AC:L), requiring low privileges (PR:L), no user interaction (UI:N), scope changed (S:C), and high impact on confidentiality, integrity, and availability (C:H/I:H/A:H). This means an attacker with limited local access can exploit the vulnerability without user interaction to gain elevated privileges and potentially compromise the device. Although no known exploits are currently reported in the wild, the vulnerability poses a significant risk due to the widespread use of Apple mobile devices and the critical role of sandboxing in maintaining system security. Apple has addressed the issue by implementing additional sandbox restrictions in the fixed versions. The vulnerability underscores the importance of robust authorization checks in sandboxed environments, especially for automation features like shortcuts that can execute complex tasks.

The impact of CVE-2025-43358 is substantial for organizations and individuals relying on Apple iOS and iPadOS devices. Exploitation allows a local attacker or malicious shortcut to bypass sandbox restrictions, potentially leading to unauthorized access to sensitive data, modification or deletion of critical files, and disruption of system availability. This could facilitate privilege escalation, data exfiltration, or installation of persistent malware. For enterprises, this vulnerability threatens the confidentiality and integrity of corporate data accessed or stored on mobile devices, undermining mobile device management (MDM) security controls. The ability to bypass sandboxing also increases the risk of lateral movement within networks if compromised devices connect to corporate resources. Given the high CVSS score and the lack of required user interaction, attackers could automate exploitation in targeted attacks or malware campaigns. 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 rapidly once the vulnerability is public. Overall, the vulnerability poses a critical risk to privacy, data protection, and operational continuity for organizations worldwide using affected Apple platforms.

To mitigate CVE-2025-43358, organizations should immediately prioritize updating all affected Apple devices to iOS 18.7, iPadOS 18.7, or the corresponding patched macOS versions (Sequoia 15.7, Sonoma 14.8, Tahoe 26). Enforce strict update policies to ensure timely deployment of security patches across all managed devices. Limit the use of shortcuts, especially those from untrusted sources, by restricting shortcut installation permissions and auditing existing shortcuts for suspicious or overly permissive actions. Employ mobile device management (MDM) solutions to enforce security configurations that restrict shortcut capabilities and sandbox access. Monitor device logs and behavior for anomalies related to shortcut execution or sandbox violations. Educate users about the risks of installing shortcuts from unknown sources and encourage reporting of unusual device behavior. Additionally, implement network segmentation and zero-trust principles to reduce the impact of a compromised device on broader enterprise systems. Regularly review and update security policies to address emerging threats related to automation and sandbox bypass techniques.
