The vulnerability CVE-2025-58966 affects Basix NEX-Forms LITE (versions before 8.2) and is classified as a reflected Cross-site Scripting (XSS) flaw. It occurs due to improper neutralization of input during web page generation, enabling attackers to inject and execute arbitrary scripts in users' browsers. The CVSS v3.1 base score is 7.1, indicating high severity, with network attack vector, low attack complexity, no privileges required, user interaction required, scope changed, and impacts on confidentiality, integrity, and availability at low levels.

Successful exploitation of this vulnerability can allow attackers to execute arbitrary scripts in the context of the affected web application, potentially leading to partial disclosure of sensitive information, modification of data, or disruption of service. The reflected nature means the attack requires a victim to interact with a crafted link or input. There are no reports of active exploitation in the wild at this time.
