- 漏洞描述

Opera contains a flaw that may allow a malicious user to spoof a trusted Web page. The issue is triggered when a remote attacker alters the opera address bar with the and location.replace functions, which will load other page contents while keeping the URL. By crafting a specially-crafted web page, a remote attacker can spoof a trusted website to trick users into visiting a malicious Web site and possibly retrieve sensitive information, resulting in a loss of integrity.
