CVE-2010-4580
Opera before 11.00 does not clear WAP WML form fields after manual navigation to a new web site, which allows remote attackers to obtain sensitive information via an input field that has the same name as an input field on a previously visited web site.
Does this matter?
Lower severity and a low EPSS score (2.23%). Track it; it rarely justifies an emergency change on its own.
