The JanStudio Claue WooCommerce theme versions up to 2.2.7 contain a reflected cross-site scripting vulnerability due to improper input neutralization during web page generation. This allows attackers to inject malicious scripts that execute in users' browsers, potentially leading to partial compromise of confidentiality, integrity, and availability of affected systems. The vulnerability is remotely exploitable without privileges but requires user interaction. The CVSS 3.1 base score is 7.1 (high severity). No official patch or remediation guidance is currently documented.

Successful exploitation of this reflected XSS vulnerability could allow attackers to execute arbitrary scripts in the context of users visiting affected web pages, potentially leading to theft of sensitive information, session hijacking, or other malicious actions impacting confidentiality, integrity, and availability. The CVSS vector indicates network attack vector, low attack complexity, no privileges required, user interaction required, and scope change, with low impact on confidentiality and integrity and low impact on availability.
