Summary
A Stored Cross-Site Scripting (XSS) vulnerability was identified in the /intranet/agenda.php endpoint of the i-Educar application. This vulnerability allows attackers to inject malicious scripts into the novo_descricao parameter. The injected scripts are stored on the server and executed automatically whenever the affected page is accessed by users, posing a significant security risk.
