CVE-2025-10552Network attack vector

Browser-session script execution via stored XSS

Published Oct 13, 2025 · Updated Oct 13, 2025

Stored XSS in 3DSwym in Dassault Systèmes 3DSwymer R2025x allows remote authenticated users to run script in a user's browser. Dassault Systèmes identifies 3DSwym as the affected component but does not disclose which stored input reaches an output context without proper neutralization. Low-privileged access is required to persist the payload, and a separate user must view the affected content; execution is confined to that user's browser session.
