CVE-2025-49893 describes a reflected Cross-site Scripting (XSS) vulnerability in the uxper Nuss software versions up to 1.3.3. The issue is due to improper neutralization of user input during web page generation, which allows attackers to inject and execute arbitrary scripts in the context of the affected web application. The CVSS v3.1 score is 7.1, indicating a high severity with network attack vector, low attack complexity, no privileges required, user interaction required, and impacts on confidentiality, integrity, and availability.

Successful exploitation of this vulnerability could allow an attacker to execute arbitrary scripts in a victim's browser, potentially leading to theft of sensitive information, session hijacking, or other malicious actions affecting confidentiality, integrity, and availability of the affected system. However, no known exploits in the wild have been reported.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should apply standard mitigations for reflected XSS such as input validation and output encoding where possible. Monitor vendor communications for updates regarding patches or official mitigations.
