The issue describes a reflected Cross-Site Scripting (XSS) vulnerability in the Jeecg Boot application. An attacker can inject malicious JavaScript code into the application via a crafted URL, which can be executed in the context of the user's browser when they visit the link. This can lead to unauthorized actions being performed on behalf of the user or sensitive information being exposed.
