The Contact Form for Plugin by Fluent Forms plugin for WordPress is vulnerable to Insecure Direct Object Reference in versions up to, and including, 5.0.8 via the addIsRenderableFilter() function due to missing validation on the publication status of a form. This makes it possible for users to render and submit forms when the form is in an 'unpublished' state.
