Feedback on this post and its mitigation advice is welcome and appreciated. To request a future article from me on web safety, feel free to contact me directly at I hope I managed to tickle your brain and to introduce a healthy dose of paranoia and website security vulnerability consciousness. It is worth mentioning that stuffing unsanitized user-defined input into an HTTP header might result in header injection, which is fairly dangerous. The lesson here is that software development doesn’t end when the appliance is deployed.
So, once more, the safety question is determined by the expertise utilization. So if you are an excellent programmer who cares about security you may write safe code. If you are a unhealthy programmer, you’ll write insecure code with whichever language you decide.

Everything is now depending on that 12-hour timer, which is counting down.
