Detailsinfo

A vulnerability classified as critical has been found in Crocoblock JetEngine Plugin up to 3.8.6.1 on WordPress. This affects the function sprintf of the component Content Types Module. The manipulation 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. The summary by CVE is:

The JetEngine plugin for WordPress is vulnerable to SQL Injection via the Custom Content Type (CCT) REST API search endpoint in all versions up to, and including, 3.8.6.1. This is due to the `_cct_search` parameter being interpolated directly into a SQL query string via `sprintf()` without sanitization or use of `$wpdb->prepare()`. WordPress REST API's `wp_unslash()` call on `$_GET` strips the `wp_magic_quotes()` protection, allowing single-quote-based injection. 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. The Custom Content Types module must be enabled with at least one CCT configured with a public REST GET endpoint for exploitation.
