This vulnerability in skygroup GoStore (versions before 1.6.4) is caused by improper neutralization of user input during web page generation, resulting in a reflected cross-site scripting (XSS) issue. An attacker can craft malicious input that is reflected in the web page without proper sanitization, enabling script execution in the victim's browser. The CVSS 3.1 score is 7.1 (high), reflecting network attack vector, low attack complexity, no privileges required, user interaction required, and impacts on confidentiality, integrity, and availability.

Successful exploitation allows an attacker to execute arbitrary scripts in the context of the victim's browser session, potentially leading to partial disclosure of sensitive information, modification of web content, and disruption of availability. The reflected XSS nature requires user interaction to trigger the attack. There are no known exploits in the wild at this time.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should apply standard XSS mitigations such as input validation and output encoding where possible. Monitor vendor channels for updates and apply patches promptly once released.
