CVE-2026-0534Network attack vector

Code execution via unneutralized part-attribute HTML

Published Jan 22, 2026 · Updated Jun 3, 2026

Stored XSS in Autodesk Fusion 2603.0 through versions before 2606.1.21 allows remote attackers to execute code through a crafted part attribute. A part attribute stores attacker-controlled HTML without neutralizing script-capable markup, and Fusion renders the value so a click executes it in the desktop process. A user must click the stored payload; successful exploitation reads local files or runs arbitrary code with the current process's privileges.
