WordPress 插件“Unlimited Elements For Elementor”在 2.0.16 及更早版本中，其 'addontype' 参数存在 SQL 注入漏洞。该漏洞源于对用户输入参数的转义不足，以及 getWhereString() 函数中现有 SQL 查询缺乏充分的预处理。具体而言，当该参数以数组形式提供时，数组的零号元素会被直接用作 SQL 比较运算符，并未经消毒处理就拼接进 WHERE 子句；同时，normalizeAjaxInputData() 函数会移除 WordPress 的魔术引

Vulnerability Title
Unlimited Elements For Elementor <= 2.0.16 - Unauthenticated SQL Injection
Source: CVE Program / CVE List V5
Vulnerability Description
The Unlimited Elements For Elementor plugin for WordPress is vulnerable to SQL Injection via the 'addontype' parameter in versions up to, and including, 2.0.16. This is due to insufficient escaping on the user-supplied parameter and the lack of sufficient preparation on the existing SQL query in the getWhereString() function; when the parameter is supplied as an array, element zero is used verbatim as the SQL comparison operator and concatenated into the WHERE clause without sanitization, while normalizeAjaxInputData() strips WordPress's magic_quotes protection from the value. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
