The CVSS 3.1 vector indicates network attack vector, low attack complexity, low privileges required, user interaction required, and scope change.

Successful exploitation could allow an attacker to execute arbitrary scripts in the context of users viewing the affected pages, potentially leading to information disclosure, modification of content, or disruption of service. The impact affects confidentiality, integrity, and availability to a limited extent as indicated by the CVSS score of 6.5.
