💻 Affected Systems
- Adobe Illustrator
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Full system compromise via arbitrary code execution with user privileges, potentially leading to data theft, ransomware deployment, or lateral movement.
Likely Case
Local privilege escalation or malware installation if user opens malicious SVG file, potentially leading to data exfiltration.
If Mitigated
Limited impact with proper application sandboxing and user awareness preventing file execution.
🎯 Exploit Status
Requires user to open malicious SVG file; no known public exploits as of advisory publication.
🛠️ Fix & Mitigation
✅ Official Fix
