CURCY WooCommerce Multi Currency Currency Switcher Unauthenticated SQL Injection Vulnerability

A SQL injection vulnerability has been identified in the CURCY - WooCommerce Multi Currency - Currency Switcher plugin for WordPress, affecting all versions through 2.3.6. The vulnerability arises from inadequate escaping of user-supplied data in the 'wc_filter_price_meta[where]' parameter, coupled with a lack of proper preparation in the 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 an attacker can manipulate SQL queries to access or modify database information. In this case, it could be used to extract sensitive data from the database.

Remediation

Users are advised to update the CURCY - WooCommerce Multi Currency - Currency Switcher plugin to version 2.3.7 or a newer patched version.
