Payment Vulnerability

### Vulnerability Description

When intercepting the payment page, it is possible to manipulate the payment amount by altering the data transmitted. This vulnerability arises because sensitive information is exposed in the URL, making it susceptible to unauthorized modifications, posing a significant security risk to the project.

### Proposed Fixes

- **Data Transmission Method:** Ensure that sensitive data, especially payment-related information, is transmitted using the POST method rather than being exposed in the URL. POST requests encapsulate data within the request body, providing a more secure means of transmitting sensitive information.

- **Data Encryption:** Implement robust data encryption techniques to encode the information being transmitted. Encryption adds an additional layer of security by scrambling the data, making it unreadable to unauthorized parties. This ensures that even if intercepted, the data remains confidential and secure.

These measures will enhance the security posture of the payment page, safeguarding sensitive information from unauthorized access and manipulation.
