Technical details
The vulnerability is a SQL Injection (SQLi) flaw in the getWhereString() function where the 'addontype' parameter is insufficiently escaped. When supplied as an array, the first element is used verbatim as a SQL comparison operator and concatenated directly into the WHERE clause without sanitization. Additionally, the normalizeAjaxInputData() function strips WordPress's magic_quotes protection from user input. The attack requires network access to the plugin's AJAX handlers but no authentication. An unauthenticated attacker can append arbitrary SQL queries to extract sensitive database records. A patch is required from the plugin developers.
