What it is

⚡ A crafty sequence of unsupported characters can wipe out your webserver's user storage! This low-privileged remote attack turns the admin into a default setup with a known password — talk about starting over! 🔥 Think of it like a restaurant where a patron requests a super weird dish that causes the chef to toss out the entire menu and revert to a plain cheese sandwich — no other diners are happy with that! An attacker can delete all previously configured users, effectively locking you out and replacing them with a default Admin account. This means unauthorized access and potential misuse of sensitive data, leading to chaos in your system. Protecting your webserver is absolutely vital!
