The CVSS 3.1 vector indicates network attack vector, low attack complexity, low privileges required, user interaction required, and scope change with low impact on confidentiality, integrity, and availability.

Successful exploitation could allow an attacker to execute arbitrary scripts in the context of other users, potentially leading to partial disclosure of information, modification of data, or disruption of service. The impact is rated medium with a CVSS score of 6.5. There are no known active exploits in the wild currently.
