Secunia has reported an injection vulnerability issue involving Opera 7.54.
In testing this with Opera 7.60 Technology Preview 4 for Windows, I am unable to reproduce this.
Whether Opera's popup blocker was set to block all popups or to block unrequested popups, it correctly blocked the popups it should have and displayed that fact. Set to block unreqeuested popups, it correctly displayed the USA Today Day In Pictures popup, which was requested, displaying the information from USA Today, not Secunia.
