This vulnerability in Pierre Lannoy Sessions (versions <= 3.2.0) involves improper neutralization of input during web page generation, leading to stored cross-site scripting (XSS). An attacker could inject malicious scripts that are stored and later executed in the context of users' browsers, potentially impacting confidentiality, integrity, and availability to a limited extent. The CVSS 3.1 vector indicates network attack vector, low attack complexity, high privileges required, user interaction required, and a scope change with low impact on confidentiality, integrity, and availability.

Successful exploitation could allow an attacker with high privileges and requiring user interaction to execute stored malicious scripts in the context of other users, potentially leading to limited data disclosure, modification, or disruption of service. The impact is rated as medium severity with limited confidentiality, integrity, and availability impact.
