The HQ60 Fidelity Card product by TRe Technology And Research S.r.l. suffers from a reflected cross-site scripting (XSS) vulnerability due to improper input neutralization during web page generation. This allows attackers to inject malicious scripts that could be executed in the context of a victim's browser. The issue affects all versions up to 1.8. The CVSS 3.1 vector indicates the vulnerability is remotely exploitable over the network without privileges, requires user interaction, and impacts confidentiality, integrity, and availability to a limited extent.

Successful exploitation of this reflected XSS vulnerability could allow an attacker to execute arbitrary scripts in the context of a user's browser session. This may lead to limited disclosure of information, modification of data, or disruption of service. The CVSS score of 7.1 reflects a high severity impact on confidentiality, integrity, and availability. However, no known exploits in the wild have been reported to date.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should exercise caution with untrusted input and consider implementing web application firewall (WAF) rules to detect and block reflected XSS attempts. Monitor vendor communications for updates regarding patches or official mitigations.
