This vulnerability in xili-tidy-tags (<= 1.12.06) is a reflected cross-site scripting (XSS) issue caused by improper input neutralization during web page generation. An attacker could craft malicious input that, when reflected in the web page, executes arbitrary scripts in the context of the victim's browser. The CVSS 3.1 base score is 7.1, indicating high severity, with network attack vector, low attack complexity, no privileges required, user interaction required, scope changed, and impacts on confidentiality, integrity, and availability.

Successful exploitation could allow an attacker to execute arbitrary scripts in the context of a victim's browser, potentially leading to information disclosure, session hijacking, or other impacts on confidentiality, integrity, and availability of the affected system or user data. The reflected nature requires user interaction to trigger the vulnerability.

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 channels for updates regarding patches or official mitigations.
