Is it necessary for me to manually sanitize all user inputs, or does Angular handle this process automatically?
In my login form, the data is sent to the server upon submission. Do I need to explicitly sanitize the data, or does Angular take care of sanitizing all input fields for me?
Thank you for asking these questions, they can be quite valuable to others. It is important to remember that the back end should never fully trust the front end, whether it is using a framework or a custom library – nothing is foolproof. If there are vulnerabilities in your back end system, malicious actors will exploit them without hesitation, bypassing any front end protections and making direct requests to endpoints under false pretenses.
As @etarhan suggested, please take a look at this resource: https://angular.io/guide/security
It is not advisable to have sanitization on the frontend, as users can easily manipulate it in their browser or during request transmission. It's best to handle sanitization on the backend where it cannot be altered by the user.
Additionally, I highly suggest utilizing a framework for your backend language instead of creating everything from scratch.
