⚠️ A simple user switch could lead to privilege escalation in Cygwin! Before version 2.5.0, it’s like a bouncer who forgets to check IDs when someone changes clothes. 🦸♂️ Imagine a restaurant where the chef can just don a waiter’s uniform and start ordering the kitchen around without anyone noticing. That’s what happens here when permission updates aren’t handled properly in Cygwin. An attacker could take advantage of this oversight to gain elevated privileges, potentially altering system settings or accessing sensitive data. This might not sound devastating, but it opens the door for further exploits that could compromise the whole system!
