The vulnerability CVE-2025-24721 affects the Easy YouTube Gallery plugin (versions up to 1.0.4) by Aleksandar Urošević. It is a stored cross-site scripting (XSS) issue caused by improper neutralization of input during web page generation. This flaw allows attackers with at least low privileges and requiring user interaction to inject malicious scripts that execute in the context of other users, potentially leading to partial compromise of confidentiality, integrity, and availability. The CVSS 3.1 base score is 6.5 (AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:L). No patch or official fix information is currently available from the vendor or other sources.

Successful exploitation of this stored XSS vulnerability could allow an attacker to execute arbitrary scripts in the browsers of users who view the affected pages. This may lead to partial disclosure of sensitive information, modification of displayed content, or disruption of availability. The vulnerability requires low privileges and user interaction, and it affects confidentiality, integrity, and availability to a limited extent as reflected by the CVSS score.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should consider restricting access to the plugin's input interfaces to trusted users only and apply web application firewall (WAF) rules to detect and block potential XSS payloads. Monitor vendor channels for updates and apply patches promptly once available.
