The Pinpoint Booking System – #1 WordPress Booking Plugin plugin for WordPress is vulnerable to SQL Injection via the 'language' parameter in all versions up to, and including, 2.9.9.5.2 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with Subscriber-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

The DOP Shortcodes WordPress plugin through 1.2 does not validate and escape some of its shortcode attributes before outputting them back in a page/post where the shortcode is embed, which could allow users with the contributor role and above to perform Stored Cross-Site Scripting attacks

SQL injection vulnerability in dopbs-backend-forms.php in the Booking System (Booking Calendar) plugin before 1.3 for WordPress allows remote authenticated users to execute arbitrary SQL commands via the booking_form_id parameter to wp-admin/admin-ajax.php.
