Siemens PLC XSS via Unsanitized Trace File Import
CVE-2026-63353 Published on October 13, 2026

Affected devices do not properly sanitize comment fields contained in imported trace files before rendering them 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. Successful exploitation could allow attacker-controlled JavaScript to execute in the users browser session and perform PLC operations through the web server within the scope of the users authorization.
