The vulnerability CVE-2025-31446 in jiangmiao WP Cleaner plugin (versions <= 1.1.5) is a reflected Cross-site Scripting (XSS) flaw caused by improper input neutralization during web page generation. This allows an attacker to craft malicious input that is reflected in the web page without proper sanitization, enabling script execution in users' browsers. The CVSS 3.1 base score is 7.1, indicating high severity with network attack vector, low attack complexity, no privileges required, user interaction required, scope changed, and impacts on confidentiality, integrity, and availability at a low level.

Successful exploitation of this vulnerability could allow attackers to execute arbitrary scripts in the context of the victim's browser, potentially leading to theft of sensitive information, session hijacking, or other malicious actions affecting confidentiality, integrity, and availability to a limited extent. The reflected nature requires user interaction to trigger the attack.
