scripts into the `nome` 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. The application fails to properly validate and sanitize user inputs in the `adicionar_alergia.php` parameter. This lack of validation allows attackers to inject malicious scripts, which are then stored on the server. Whenever the affected page is accessed, the malicious payload is executed in the victim's browser, potentially compromising the user's data and system. This issue has been addressed in version 3.2.6. All users are advised to upgrade. There are no known workarounds for this vulnerability.
