Incorrect origin serialization of URLs with IPv6 addresses could lead to incorrect security checks

⚠️ A sneaky URL serialization issue with IPv6 addresses could trip up security checks in Firefox versions lower than 76! Think of it like a hotel receptionist who misfiles guest reservations—if they can’t match the right room number with the correct booking, they might accidentally let the wrong person into a suite. With URLs, this miscommunication can lead to unsecured access to private areas online. An attacker could exploit this vulnerability to bypass security checks, potentially gaining access to restricted resources they shouldn't see. While not currently known to be exploited, the implications are concerning because a simple misconfiguration can lead to unauthorized access. This could expose sensitive data or even allow malicious manipulation.
