Popup WordPress Plugin SQL Injection Vulnerability

A SQL injection vulnerability has been identified in the Popup – MailChimp, GetResponse and ActiveCampaign Integrations plugin for WordPress, affecting all versions through 3.2.6. The vulnerability arises from inadequate escaping of user-supplied data in the 'id' parameter of the 'upc_delete_db_record' AJAX action, coupled with a lack of proper preparation for the existing SQL query. This flaw allows unauthenticated attackers to inject additional SQL commands into existing queries, potentially leading to the extraction of sensitive information from the database.

Impact

Exploitation of this vulnerability allows for SQL injection, where attackers can manipulate SQL queries to access or modify database information. In this case, it could be used to extract sensitive data from the database.
