📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Full system compromise with attacker gaining complete control over the affected system, potentially leading to data theft, ransomware deployment, or lateral movement within the network.
Likely Case
Local privilege escalation or remote code execution when a user opens a malicious Photoshop file, leading to malware installation or data exfiltration.
If Mitigated
Limited impact if proper application whitelisting, network segmentation, and least privilege principles are implemented.
🎯 Exploit Status
Exploitation requires user interaction (opening a malicious file). No public exploit code was available at disclosure time.
