This vulnerability in Digihood HTML Sitemap (<= 3.1.1) is caused by improper neutralization of input during web page generation, resulting in reflected cross-site scripting (XSS). An attacker can craft a malicious URL that, when visited by a user, executes arbitrary scripts in the victim's browser. The CVSS 3.1 score is 7.1 (High), with attack vector network, low attack complexity, no privileges required, user interaction required, and impacts on confidentiality, integrity, and availability.

Successful exploitation can allow attackers to execute arbitrary scripts in the context of the affected web application, potentially leading to theft of user data, session hijacking, or other malicious actions affecting confidentiality, integrity, and availability. However, exploitation requires user interaction and no known exploits are currently reported.

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 rules to detect and block reflected XSS attempts. Monitor vendor channels for updates regarding patches or official mitigations.
