This vulnerability in LambertGroup's SHOUT HTML5 Radio Player allows reflected cross-site scripting due to improper input neutralization during web page generation. It affects versions up to 3.5.4 and can be triggered via crafted input that is reflected in the web interface without proper sanitization. The CVSS 3.1 base 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 could allow an attacker to execute arbitrary scripts in the context of the affected application, potentially leading to partial disclosure of information, modification of data, or disruption of service. The reflected XSS nature requires user interaction to trigger the malicious payload. No known active exploitation has been reported.
