A security issue exists in FBX that could lead to remote code execution. The vulnerability is related to errors in processing input data, which can be exploited by opening a specially crafted malicious file. To mitigate this issue, the ability to insert FBX files has been disabled in Word, Excel, PowerPoint, and Outlook for Windows and Mac. 3D models in Office documents that were previously inserted from a FBX file will continue to work as expected unless the Link to File option was chosen at insert time.
