Deeper analysis
CVE-2025-23647 is an Improper Neutralization of Input During Web Page Generation vulnerability, classified as Reflected Cross-site Scripting (XSS) under CWE-79, in the Ariagle WP-Clap WordPress plugin (wp-clap). Published on 2025-02-14, it affects all versions of WP-Clap from n/a through 1.5 inclusive. The issue stems from inadequate input sanitization during web page generation, enabling malicious script injection.
Attackers can exploit this vulnerability remotely over the network (AV:N) with low attack complexity (AC:L), no privileges required (PR:N), but user interaction is needed (UI:R), such as clicking a malicious link. Successful exploitation changes scope (S:C) and allows low-impact effects on confidentiality, integrity, and availability (C:L/I:L/A:L), yielding a CVSS v3.1 base score of 7.1. This typically enables arbitrary JavaScript execution in the victim's browser within the site's context.
