This vulnerability in Persian Woocommerce SMS plugin (versions <= 7.1.1) is due to improper input neutralization during web page generation, resulting in reflected Cross-site Scripting (XSS). An attacker can craft malicious input that is reflected in the web page output, potentially executing arbitrary scripts in the context of the victim's browser session. The CVSS 3.1 base score is 7.1, indicating high severity with network attack vector, low attack complexity, no privileges required, user interaction needed, and impacts on confidentiality, integrity, and availability.

Successful exploitation can allow attackers to execute arbitrary scripts in the context of users visiting the affected web pages, potentially leading to theft of sensitive information, session hijacking, or other malicious actions impacting confidentiality, integrity, and availability of the affected system.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should consider applying web application firewall (WAF) rules to detect and block reflected XSS attempts and avoid clicking on suspicious links that may exploit this vulnerability.
