## Technical details

A Stored Cross-site Scripting (XSS) vulnerability exists in the Process Experience Studio component of Dassault Systèmes DELMIA Service Process Engineer (3DEXPERIENCE R2024x through R2026x). The flaw is caused by improper neutralization of user-supplied input (CWE-79) before it is stored and subsequently displayed to other users. An authenticated attacker with low privileges can inject malicious JavaScript into the application. When a victim views the affected page, the script executes within the context of their browser session, potentially allowing the attacker to steal session tokens or modify page content. The vulnerability has a CVSS score of 8.7, reflecting a high impact on confidentiality and integrity due to the 'Scope Changed' (S:C) nature of the exploit.
