WP Crowdfunding lets Subscribers create campaign posts
WP Crowdfunding before 2.2.1 exposes wp_ajax_addfrontenddata, which calls Submit_Form::frontend_data_save() and accepts the campaign form. Although the request includes the wpcf_form_action_field nonce for action wpcf_form_action, the affected code does not enforce the campaign_form_submit capability before creating a product with wp_insert_post() and crowdfunding metadata. A Subscriber can therefore create campaign posts without permission. Version 2.2.1 adds the missing capability check.
