The type of threat described is Tampering. This threat occurs when an attacker intercepts and manipulates data being sent from the client to the server, such as formdata being submitted to an API. The attacker may alter the data to change the intended operation, inject malicious content, or compromise the integrity of the system. Tampering attacks are a significant concern in secure software design because they can lead to unauthorized changes and potentially harmful actions within the application.
