## Technical details

A stored cross-site scripting (XSS) vulnerability exists in Autodesk Fusion's Library Manager when displaying HTML payloads embedded in the description field of .lbr (electronic library) files. The vulnerability is triggered when a maliciously crafted library file is imported and its description is displayed, with no apparent sanitization preventing script execution. An attacker can leverage this to read local files or execute arbitrary code in the context of the Fusion process.
