Technical details
The vulnerability is a use-after-free defect in Substance3D Stager versions 3.1.7 and earlier. This memory safety issue occurs when the application references memory that has already been freed, allowing an attacker to corrupt memory state and achieve arbitrary code execution. The attack requires user interaction—specifically, a victim must open a malicious file to trigger the flaw. The vulnerability is network-adjacent in that files could be delivered via email or download, but local exploitation context (running in the current user's privilege level) applies once the file is opened. Adobe has released security updates to address this issue.
