📋 TL;DR
Adobe InDesign versions 17.1 and earlier (macOS/Windows) and 16.4.1 and earlier (macOS/Windows) contain an out-of-bounds write vulnerability. When exploited, this allows attackers to execute arbitrary code with the privileges of the current user by tricking them into opening a malicious file. This affects all users running vulnerable versions of Adobe InDesign.

📦 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
Local privilege escalation leading to user account compromise, data exfiltration, or malware installation.
If Mitigated
Limited impact with proper application sandboxing and user privilege restrictions, though user data remains at risk.
🎯 Exploit Status
Exploitation requires user interaction (opening malicious file). No public exploit code available at disclosure.
