The WP-Recall WordPress plugin before 16.26.12 does not sanitize and escape a parameter before using it in a SQL statement, allowing admins to perform SQL injection attacks

The WP-Recall – Registration, Profile, Commerce & More plugin for WordPress is vulnerable to arbitrary shortcode execution due to a missing capability check on the 'rcl_preview_post' AJAX endpoint in all versions up to, and including, 16.26.10. This makes it possible for authenticated attackers, with Subscriber-level access and above, to execute arbitrary shortcodes.

The WP-Recall – Registration, Profile, Commerce & More plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'public-form' shortcode in all versions up to, and including, 16.26.10 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.

This requires the commerce addon to be enabled in order to exploit.

The WP-Recall – Registration, Profile, Commerce & More plugin for WordPress is vulnerable to unauthorized loss of data due to a missing capability check on the 'delete_payment' function in all versions up to, and including, 16.26.6.
