This vulnerability (CVE-2025-53559) involves improper input neutralization in the Universal Video Player - Addon for WPBakery Page Builder by LambertGroup, resulting in reflected Cross-site Scripting (XSS). The issue affects all versions up to 3.2.1. The CVSS 3.1 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. No patch or vendor advisory is currently available, and the product is not a cloud service.

Successful exploitation of this vulnerability allows an attacker to execute arbitrary scripts in the context of the victim's browser, potentially leading to theft of sensitive information, session hijacking, or other malicious actions affecting confidentiality, integrity, and availability at a low level. The reflected nature means the attack requires user interaction, such as clicking a crafted link.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should exercise caution with untrusted input and consider implementing web application firewall (WAF) rules to detect and block reflected XSS attempts. Monitor vendor channels for updates and apply patches promptly once available.
