CVE-2025-61831
📋 TL;DR
This CVE describes an out-of-bounds write vulnerability in Adobe Illustrator that could allow arbitrary code execution when a user opens a malicious file. Attackers could gain the same privileges as the current user. All users running affected Illustrator versions are at risk.
💻 Affected Systems
- Adobe Illustrator
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Full system compromise with attacker gaining the same privileges as the current user, potentially leading to data theft, ransomware deployment, or lateral movement within the network.
Likely Case
Local privilege escalation leading to data exfiltration, malware installation, or persistence mechanisms being established on the compromised system.
If Mitigated
Limited impact with proper application sandboxing and user privilege restrictions, potentially containing the exploit to the Illustrator process only.
🎯 Exploit Status
Exploitation requires user interaction (opening a malicious file). No public exploit code has been identified at this time.
