Code execution via exported design-name HTML payload
Published Apr 14, 2026 · Updated Apr 14, 2026
Stored XSS in Autodesk Fusion before 2702.1.47 allows local users to execute code by exporting a crafted design-name payload to CSV. Fusion preserves attacker-supplied HTML in a design name and exports it without neutralizing executable markup, allowing the payload to run in a script-capable context. Exploitation requires user interaction with the affected export workflow; the script runs in the current process and can read local files or execute arbitrary code.
