The ThemeGrill eStore plugin for WordPress contains a reflected Cross-site Scripting (XSS) vulnerability due to improper neutralization of input during web page generation. This flaw allows attackers to inject malicious scripts that execute when a victim views a crafted URL or page, potentially leading to information disclosure, session hijacking, or other impacts. The vulnerability affects all versions up to and including 1.6.13. The CVSS 3.1 base score is 7.1, reflecting network attack vector, low attack complexity, no privileges required, user interaction required, and impacts on confidentiality, integrity, and availability. No official patch or vendor advisory is provided in the input data.

Successful exploitation of this reflected XSS vulnerability can lead to partial compromise of confidentiality, integrity, and availability of the affected system from the perspective of the user. Attackers may execute arbitrary scripts in the context of the victim's browser, potentially leading to session hijacking, information disclosure, or manipulation of web content. However, no known exploits in the wild are reported.

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.
