Technical details

A trusted markdown injection vulnerability in the Autodesk Fusion Post Processor Utility allows arbitrary command execution when a maliciously crafted .stack.json file is processed. The vulnerability likely stems from insufficient sanitization of markdown content rendered in the VS Code extension context, where trusted rendering could execute embedded commands. Attack requires the user to open or process a malicious .stack.json file.
