The JetEngine plugin for WordPress is vulnerable to SQL injection in all versions up to and including 3.8.10.1. The listing_load_more AJAX handler accepts a filtered_query parameter that is intentionally excluded from the HMAC query signature check to support front-end filter integration. However, meta_query row values within filtered_query are not sanitized before being merged into SQL construction. This makes it possible for unauthenticated attackers to perform time-based or boolean blind SQL injection by appending a malicious meta_query value to a Load More AJAX request captured from any public Listing Grid page.
