Browser-session script execution via stored content

Published Jun 16, 2025 · Updated Jun 16, 2025

Stored XSS in Opportunity Management in Project Portfolio Manager R2023x through R2025x allows remote authenticated users to run browser scripts. Dassault Systèmes identifies the affected module and stored behavior but has not published the input field or missing output-encoding operation. Low-privileged access is required to persist content, and a separate user must view it; execution can read or alter data available to that browser session.
