Worst Case
A malicious sandboxed application could escape sandbox restrictions and access sensitive system resources, user data, or perform unauthorized actions with elevated privileges.
Likely Case
Malicious applications could bypass intended security controls to access files, network resources, or system functions they should be restricted from.
If Mitigated
With proper application vetting and security controls, the risk is limited to untrusted applications that manage to bypass App Store review or enterprise distribution controls.
🎯 Exploit Status
Exploitation requires a malicious sandboxed application to be installed and executed on the target system.
