CVE-2026-63356
What it is
Affected devices do not properly sanitize calculated signal names contained in imported CSV trace files before including them in error messages 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 resulting error message is displayed.
