What is the potential problem of overly specific form validation?

The problem with form validators is that they effectively block the user from proceeding. This, of course, is their purpose, but unless the validation rules can be and are implemented 100% flawlessly (i.e. zero false negatives), users will eventually run into unintended roadblocks.

What is the most common result of improper input validation?

Improper input validation can enable attacks and lead to unwanted behavior. Parts of the system may receive unintended input, which may result in altered control flow, arbitrary control of a resource, or arbitrary code execution.

What is the significant effect of validating user inputs?

It helps prevent malicious users from submitting invalid data. It can help improve application performance since the application doesn't have to waste time processing invalid data.
