"The version of Autodesk Fusion 360 installed on the remote host is less than or equal to 2704.1.53. It is, therefore,
affected by a man-in-the-middle vulnerability:

  - A maliciously crafted add-in, when installed and executed in Autodesk Fusion Desktop, can modify
    persistent network proxy settings without user notification or consent. A successful exploit may
    allow an attacker to redirect authenticated Fusion network traffic through an attacker-controlled
    proxy, potentially exposing sensitive information with the current user. (CVE-2026-85217)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
