The WP Visual Sitemap plugin for WordPress versions up to 1.0.2 contains a stored cross-site scripting vulnerability due to improper input neutralization during web page generation. This vulnerability (CVE-2025-53290) allows an attacker with low privileges and requiring user interaction to inject malicious scripts that can impact confidentiality, integrity, and availability. The CVSS 3.1 vector indicates network attack vector, low attack complexity, low privileges required, user interaction required, and scope changed with partial impact on confidentiality, integrity, and availability.

Successful exploitation of this vulnerability could allow an attacker to execute arbitrary scripts in the context of the affected site, potentially leading to data theft, session hijacking, or other malicious actions impacting confidentiality, integrity, and availability. However, exploitation requires user interaction and low privileges, limiting the attacker's capabilities. No known active exploits have been reported.
