Medium severity, CVSS 5.0. EPSS: 9.1% chance of exploitation in the next 30 days.

Microsoft Internet Explorer 6 omits high-bit URL-encoded characters when displaying the address bar, which allows remote attackers to spoof the address bar via a URL with a domain name that differs from an important domain name only in these characters, as demonstrated by using exam%A9ple.com to spoof example.com, aka MSRC ticket MSRC7900.
