Charitable <= 1.8.12.1 - Authenticated (Contributor+) SQL Injection via 'order' Shortcode Attribute

The Charitable – Donation & Fundraising Platform (Donation Forms, Recurring Donations & Fundraising Campaigns) plugin for WordPress is vulnerable to generic SQL Injection via 'order' Shortcode Attribute in all versions up to, and including, 1.8.12.1 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 contributor-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 [charitable_donors] shortcode is accessible to Contributor-level users via draft or pending post previews, providing an authenticated but low-privileged entry point for exploitation.
