Detailsinfo

A vulnerability classified as critical has been found in smub Charitable Plugin up to 1.8.12.1. Affected is an unknown code of the component Shortcode Handler. The manipulation of the argument order with an unknown input leads to a sql injection vulnerability. CWE is classifying the issue as CWE-89. The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

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.
