CVE-2026-85217

Authenticated traffic interception via silent proxy rewrite

Published Sep 10, 2026 · Updated Sep 10, 2026

Authorization bypass in Autodesk Fusion 2705.0.0 and later, before 2705.1.11, allows attackers to redirect authenticated traffic via a malicious proxy. The add-in execution path accepts a crafted add-in that silently writes persistent network proxy settings without obtaining user consent. The user must install and run the add-in; redirected Fusion sessions can expose information carried by the current user's authenticated network traffic.
