CVE-2025-54198
📋 TL;DR
CVE-2025-54198 is an out-of-bounds read vulnerability in Substance3D Modeler that could allow attackers to read sensitive memory contents when a victim opens a malicious file. This affects users of Substance3D Modeler versions 1.22.0 and earlier who open untrusted 3D model files.
💻 Affected Systems
- Adobe Substance3D Modeler
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
An attacker could exfiltrate sensitive data from the application's memory, potentially including authentication tokens, encryption keys, or other confidential information stored in memory during file processing.
Likely Case
Limited information disclosure from application memory, potentially revealing some internal application state or previously processed data fragments.
If Mitigated
No impact if users only open trusted files from verified sources and the application is properly patched.
🎯 Exploit Status
Exploitation requires user interaction (opening malicious file) and knowledge of memory layout. No public exploits known at this time.
