CVE-2026-10709: CWE-121 Stack-based Buffer Overflow in Autodesk FBX SDK
CVE-2026-10709 is a stack-based buffer overflow vulnerability in Autodesk FBX SDK version 2020.3.9. It occurs in the function fbxsdk::FbxIO::BinaryReadSectionHeader when parsing a maliciously crafted FBX file. Successful exploitation can allow arbitrary code execution within the context of the current process. The vulnerability has a high severity score of 7.8 and requires local access with user interaction to trigger.
AI Analysis
Technical Summary
This vulnerability involves a stack-based buffer overflow in the Autodesk FBX SDK's BinaryReadSectionHeader function. When a specially crafted FBX file is parsed, the overflow can be triggered, potentially enabling an attacker to execute arbitrary code. The affected version is specifically 2020.3.9. The CVSS 3.1 vector indicates local attack vector, low attack complexity, no privileges required, user interaction required, unchanged scope, and high impact on confidentiality, integrity, and availability.
Potential Impact
An attacker who can supply a malicious FBX file to an application using the vulnerable FBX SDK version 2020.3.9 may execute arbitrary code with the privileges of the current process. This can lead to full compromise of the affected application and potentially the host system depending on the application's privileges.
Mitigation Recommendations
No official patch or remediation is currently documented. Patch status is not yet confirmed — check the Autodesk vendor advisory for current remediation guidance. Until a fix is available, avoid processing untrusted FBX files with the affected SDK version.
