## Overview

Affected devices do not properly sanitize signal names contained in imported CSV trace files before rendering them in selection menus on the Trace page.

This could allow an attacker to social engineer an authorized user who holds the function right “Read diagnostics” into importing a specially crafted trace file. Attacker-controlled JavaScript could be executed in the user’s browser session when the user subsequently interacts with an affected selection menu.
