## Description

The Flow-Flow Social Feed & Social Wall plugin for WordPress is vulnerable to Cross-Site Request Forgery via the flow_flow_moderation_apply_action AJAX action in all versions up to, and including, 5.0.5, due to missing nonce validation in the moderation_apply() function. This makes it possible for unauthenticated attackers to approve, reject or pin feed posts and change their call-to-action links and text, if they can trick a stream moderator or administrator into performing an action such as clicking a link.
