CVE-2026-83962 is a stack-based buffer overflow vulnerability (CWE-121) in Adobe Substance3D - Modeler. This vulnerability allows an attacker to execute arbitrary code in the context of the current user if the victim opens a maliciously crafted file. The vulnerability affects versions >=0 and <=1.22.6. The CVSS v3.1 base score is 7.8, with attack vector local, low attack complexity, no privileges required, user interaction required, and high impact on confidentiality, integrity, and availability.

Successful exploitation can lead to arbitrary code execution with the privileges of the current user, potentially compromising confidentiality, integrity, and availability of the affected system. However, exploitation requires user interaction, limiting the attack vector to scenarios where a user opens a malicious file.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or patch links are provided in the available data. Until a patch is available, users should avoid opening untrusted files with Substance3D - Modeler versions up to 1.22.6.
