Deeper analysis

CVE-2025-23576 is an Improper Neutralization of Input During Web Page Generation vulnerability, classified as Reflected Cross-site Scripting (XSS) under CWE-79, in the WP Intro.JS (wp-intro-js-tours) WordPress plugin developed by cfuze. This issue affects all versions of the plugin from n/a through 1.1 inclusive, as published on 2025-03-03 with a CVSS v3.1 base score of 7.1 (High).

Attackers can exploit this vulnerability remotely over the network (AV:N) with low attack complexity (AC:L), no privileges required (PR:N), but it requires user interaction (UI:R), such as clicking a malicious link. Exploitation changes the security scope (S:C) and enables low-impact consequences on confidentiality, integrity, and availability (C:I:A:L), allowing arbitrary script execution in the victim's browser context, potentially leading to session hijacking or data theft.
