📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise via arbitrary code execution leading to data theft, ransomware deployment, or persistent backdoor installation.
Likely Case
Malware installation or data exfiltration when users open specially crafted malicious project files.
If Mitigated
Limited impact if users only open trusted files from verified sources and have endpoint protection.
🎯 Exploit Status
Exploitation requires user interaction (opening malicious file) and crafting a file that triggers the out-of-bounds write.
