This vulnerability in Church Admin (<= 4.0.26) involves improper neutralization of input during web page generation, resulting in a cross-site scripting (XSS) flaw. An attacker with low privileges and requiring user interaction could exploit this to execute arbitrary scripts, potentially impacting confidentiality, integrity, and availability of the affected system. The CVSS 3.1 vector is AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:L, reflecting network attack vector, low attack complexity, low privileges required, user interaction needed, scope change, and partial impact on confidentiality, integrity, and availability.

Successful exploitation could allow an attacker to execute arbitrary scripts in the context of the victim's browser, potentially leading to information disclosure, modification of data, or disruption of service. The vulnerability affects confidentiality, integrity, and availability to a limited extent. No known active exploits have been reported.
