Description

The Charitable plugin for WordPress is vulnerable to unauthorized access via the 'charitable_builder_field_content_preview' AJAX action in versions 1.8.0 up to, and including, 1.8.13, due to a missing capability check and missing nonce verification in the charitable_builder_field_content_preview() function. This makes it possible for authenticated attackers, with Subscriber-level access and above, to render campaign builder field previews from data they supply. For the donor wall field, those values are concatenated without escaping into a string passed to do_shortcode(), so the attacker can run arbitrary shortcodes. Attackers can also expose content from the builder settings (campaign_settings_v2 meta) of any campaign, such as its description, including draft and private campaigns.
