Opera browser before version 10 may show wrong site address

CVE-2009-3047 · published 17 years ago
Summary

In older versions of the Opera web browser, the address bar can sometimes keep the previous website's name when it is collapsed, showing an incorrect URL. This could let attackers make a site appear trustworthy while it is not. Update Opera to version 10 or later, or avoid using the collapsed address bar in older versions.
