📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
An attacker could extract sensitive information from application memory, potentially including authentication tokens, file contents, or other confidential data.
Likely Case
Limited information disclosure from memory when users open specially crafted malicious files.
If Mitigated
No impact if users only open trusted files or have patched to version 3.1.4 or later.
🎯 Exploit Status
Requires user interaction (opening malicious file) and successful exploitation depends on memory layout and file content.
