CVE-2026-0661
📋 TL;DR
This vulnerability allows attackers to execute arbitrary code by tricking users into opening malicious RGB files in Autodesk 3ds Max. Users who open untrusted RGB files in affected versions of 3ds Max are at risk of complete system compromise.
💻 Affected Systems
- Autodesk 3ds Max
📦 What is this software?
3ds Max by Autodesk
⚠️ Risk & Real-World Impact
Worst Case
Full system compromise with attacker gaining the same privileges as the 3ds Max user, potentially leading to data theft, ransomware deployment, or lateral movement.
Likely Case
Local privilege escalation leading to malware installation, data exfiltration, or persistence mechanisms on the affected workstation.
If Mitigated
Limited impact if file execution is blocked or user runs with minimal privileges, though some data loss or corruption may still occur.
🎯 Exploit Status
Exploitation requires user interaction to open a malicious file. No public exploit code is currently available.
