This vulnerability in HT Plugins HT Contact Form 7 (up to version 2.8.2) involves improper neutralization of input during web page generation, resulting in stored cross-site scripting (XSS). An attacker can inject malicious scripts that persist and execute when users access affected pages. The CVSS 3.1 base score is 7.1, reflecting network attack vector, low attack complexity, no privileges required, user interaction required, scope change, and low impacts on confidentiality, integrity, and availability.

Successful exploitation allows an attacker to execute arbitrary scripts in the context of the affected web application, potentially leading to partial compromise of confidentiality, integrity, and availability of the application or user data. The scope change indicates that the vulnerability can affect resources beyond the initially vulnerable component.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance.
