The LambertGroup Universal Video Player - Addon for WPBakery Page Builder contains a reflected Cross-site Scripting (XSS) vulnerability (CVE-2025-48170) due to improper input neutralization during web page generation. This flaw affects all versions up to 3.2.1. The vulnerability allows attackers to inject malicious scripts that execute when a user interacts with crafted content, potentially leading to partial compromise of confidentiality, integrity, and availability. The CVSS 3.1 score is 7.1, reflecting network attack vector, low attack complexity, no privileges required, user interaction required, and scope change with low impact on confidentiality, integrity, and availability. No patch or vendor advisory is currently provided, and no exploits are known in the wild.

Successful exploitation of this reflected XSS vulnerability can lead to execution of arbitrary scripts in the context of the victim's browser, potentially allowing theft of sensitive information, session hijacking, or other malicious actions that impact confidentiality, integrity, and availability to a limited extent. The vulnerability requires user interaction and can be exploited remotely over the network without authentication.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should consider disabling or limiting use of the affected plugin to reduce exposure. Implementing web application firewall (WAF) rules to detect and block reflected XSS payloads may provide temporary mitigation. Monitor LambertGroup and WPBakery Page Builder advisories for updates.
