An attacker who successfully exploited the vulnerability could run scripts in the context of the targeted user. The attacks could allow the attacker to read content that the attacker is not authorized to read, execute malicious code, and use the victim's identity to take actions on the site on behalf of the user, such as change permissions and delete content.
