CVE-2023-46471Public exploitNetwork attack vector

Browser script execution via unsanitized ScriptViewer content

Published Nov 20, 2023 · Updated Jun 10, 2025

Stored XSS in the ScriptViewer component of Yamcs 5.8.6 allows remote authenticated users to execute JavaScript in a viewer's browser. The component renders scriptContainer text without sanitizing HTML tags, so stored markup executes when the script is loaded or reopened. Exploitation requires permission to load or save a script and user interaction by a viewer who navigates to it; impact is confined to that browser context.
