Attackers can exploit this vulnerability over the network with low complexity if they have high privileges, such as administrative access to the Sitefinity backend, and can induce user interaction, like clicking a malicious link. Successful exploitation changes scope and enables high-impact compromise of confidentiality, integrity, and availability, potentially allowing attackers to execute arbitrary scripts in the context of the administrative session.
