⚠️ Risk & Real-World Impact
Worst Case
Attackers could install malicious applications that compromise device integrity, steal sensitive data, or establish persistent access to the system.
Likely Case
Users might be tricked into installing unwanted or malicious applications through social engineering, leading to privacy violations or reduced device performance.
If Mitigated
With proper user awareness and security controls, the impact is limited since user action is required, though the permission bypass remains a concern.
🎯 Exploit Status
Exploitation requires user interaction (such as clicking a link or approving an action), which adds a layer of complexity but doesn't eliminate the risk entirely.
