#317476 Account Takeover in Periscope TV

Periscope's Twitter OAuth login echoed the Host header into its redirect target, so a request carrying Host set to attacker.com/www.periscope.tv sent the OAuth callback to the attacker. A victim who authorises the resulting link hands over their oauth verifier, letting the attacker finish the flow and take over the Periscope account.
