The WP Crowdfunding WordPress plugin before 2.2.1 does not verify order ownership before returning order details, allowing any authenticated users such as Subscribers to read the personal data of any WooCommerce order and enumerate every order in the store.

The WP Crowdfunding plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check on the downloaddata action in all versions up to, and including, 2.1.14. This makes it possible for authenticated attackers, with subscriber-level access and above, to download all of a site's post content when WooCommerce is installed.

The WP Crowdfunding plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the wp-crowdfunding/search block in all versions up to, and including, 2.1.15 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

The WP Crowdfunding plugin for WordPress is vulnerable to unauthorized plugin installation due to a missing capability check on the installwoocommerceplugin() function action in all versions up to, and including, 2.1.12. This makes it possible for authenticated attackers, with Subscriber-level access and above, to install WooCommerce. This has a limited impact on most sites because WooCommerce is a requirement.

The WP Crowdfunding plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's wpcfdonate shortcode in all versions up to, and including, 2.1.11 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
