📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Full system compromise with attacker gaining the victim's privileges, allowing data theft, lateral movement, and persistent access.
Likely Case
Arbitrary code execution with user-level privileges, leading to data exfiltration, malware installation, or system disruption.
If Mitigated
Application crash causing denial of service without code execution if exploit fails or controls block document execution.
🎯 Exploit Status
Exploitation requires user interaction (opening malicious document); no authentication bypass needed.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 9.2.1.1 or later
