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

Successful exploitation of this vulnerability can lead to execution of arbitrary scripts in the context of the affected web application, potentially allowing an attacker to steal sensitive information, manipulate data, or disrupt availability. The impact is rated as medium severity with partial impact on confidentiality, integrity, and availability. No known exploits are reported in the wild.
