This vulnerability in Contact Form by Supsystic (<= 1.7.28) involves improper neutralization of input during web page generation, leading to stored cross-site scripting (XSS). An attacker with high privileges and requiring user interaction can exploit this to execute arbitrary scripts in the context of the affected application. The CVSS vector indicates network attack vector, low attack complexity, high privileges required, user interaction required, and impacts confidentiality, integrity, and availability at a low to medium level.

Successful exploitation could allow an attacker with high privileges to inject malicious scripts that execute in the context of users viewing the affected pages, potentially leading to data disclosure, modification, or disruption of service. The impact is rated medium with partial loss of confidentiality, integrity, and availability.

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