Hijacking Opera's Native Page using malicious RSS payloads

Hijacking Opera’s Native Page using malicious RSS payloads

Untrusted RSS feed content is rendered in Opera's Feed Subscription Page, a native page running in a higher-privileged zone than the internet zone. Escaping that page's HTML tag whitelist and sanitiser lets a crafted feed run script there and call native functions such as opera.feeds.subscribeNative, taking control of the browser. Fixed in Opera 10.01.
