Name of the Vulnerable Software and Affected Versions: Form Tools versions 3.0.20 and earlier

Description: An issue was discovered in Form Tools where the customer's name and last name fields are vulnerable to XSS payload insertion. This stored XSS can be triggered in the admin panel when the admin tries to view the client list, potentially leading to the extraction of the admin's PHPSESSID cookie.

Recommendations: For versions 3.0.20 and earlier, consider disabling the ability for customers to change their name and last name fields until a patch is available. Restrict access to the admin panel to minimize the risk of exploitation. Avoid displaying the client list in the admin panel until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
