The vulnerability CVE-2025-22566 affects the ULTIMATE VIDEO GALLERY plugin by extendyourweb, specifically versions up to 1.4. It is a reflected Cross-site Scripting (XSS) flaw caused by improper input neutralization during web page generation. This 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 v3.1 base score is 7.1, indicating high severity, with network attack vector, low attack complexity, no privileges required, user interaction required, and scope changed. No patch or official remediation guidance is currently available.

Successful exploitation of this reflected XSS vulnerability can allow attackers to execute arbitrary scripts in the context of users' browsers, potentially leading to partial disclosure of information, modification of data, or disruption of service. The CVSS score of 7.1 reflects these impacts as high severity but not critical. There are no known exploits in the wild at this time.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should consider applying web application firewall (WAF) rules to detect and block reflected XSS attempts and avoid clicking on suspicious links that may exploit this vulnerability.
