🚨 A password reset is just a domain name away! If you own 'placeholder.org', you could easily reset passwords for clients like 'test'. Think of it like a restaurant where a rogue chef can impersonate any diner just by knowing their table number — they can change orders and sneak into the kitchen without anyone batting an eye! This vulnerability is absolutely devastating! An attacker controlling the domain could reset a client's password, log in, and access sensitive information, leaving users and businesses wide open to data breaches and unauthorized actions.
