CVE-2025-23556 describes a reflected cross-site scripting (XSS) vulnerability in netbitsolutions Push Envoy Notifications up to version 1.0.0. The issue is caused by improper neutralization of input during web page generation, which allows an attacker to inject and execute arbitrary scripts in the context of the affected application. 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, scope changed, and impacts on confidentiality, integrity, and availability at a low level.

Successful exploitation of this vulnerability could allow an attacker to execute arbitrary scripts in the victim's browser, potentially leading to partial disclosure of sensitive information, modification of data, or disruption of service. The reflected nature of the XSS means the attack requires user interaction, such as clicking a crafted link. The overall impact is rated as high severity based on the CVSS score of 7.1.
