The WP Test Email plugin for WordPress, developed by Boopathi Rajan, contains a reflected XSS vulnerability due to improper input neutralization during web page generation. This vulnerability affects all versions up to 1.1.7. An attacker could exploit this flaw by crafting a malicious link that, when visited by a user, executes arbitrary scripts in the context of the victim's browser session. The CVSS 3.1 base score is 7.1, reflecting network attack vector, low attack complexity, no privileges required, user interaction required, scope changed, and low to high impacts on confidentiality, integrity, and availability.

Successful exploitation of this vulnerability could allow an attacker to execute arbitrary scripts in the context of the victim's browser, potentially leading to information disclosure, session hijacking, or other malicious actions impacting confidentiality, integrity, and availability of the affected system or user data. However, no known exploits are reported in the wild.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should consider disabling or removing the WP Test Email plugin if feasible. Additionally, applying web application firewall (WAF) rules that detect and block reflected XSS payloads may provide temporary mitigation.
