Unauthenticated SQL Injection in JetSmartFilters <= 3.8.1 versions.

AnalysisAI

Unauthenticated SQL injection in the JetSmartFilters WordPress plugin (versions ≤ 3.8.1) allows remote attackers to inject arbitrary SQL queries against the underlying WordPress database without any authentication or user interaction. The CVSS 9.3 score reflects a scope-changing flaw with high confidentiality impact and low availability impact, and no public exploit has been identified at time of analysis. The vulnerability was disclosed via Patchstack and affects a popular Crocoblock/JetImpex filtering plugin widely deployed on WordPress sites.

Technical ContextAI

JetSmartFilters (vendor: JetImpex Inc., part of the Crocoblock JetPlugins suite) is a WordPress plugin that provides AJAX-driven filtering widgets for WooCommerce, Elementor, and other catalog/grid implementations. Because filter parameters are passed through admin-ajax.php or REST endpoints and reflected into SQL statements built against $wpdb, a CWE-89 SQL Injection arises when user-controlled filter inputs (commonly sort, taxonomy, meta or range parameters) are concatenated into queries instead of being parameterized via $wpdb->prepare(). The 'Scope: Changed' designation in the CVSS vector indicates the injection reaches data or components beyond the vulnerable plugin context - typical of WordPress SQLi where the shared database holds user credentials, secrets, and content for the entire site.

RemediationAI

Upgrade JetSmartFilters to a release later than 3.8.1 as published by Crocoblock/JetImpex - consult the Patchstack advisory at https://patchstack.com/database/wordpress/plugin/jet-smart-filters/vulnerability/wordpress-jetsmartfilters-plugin-3-8-1-sql-injection-vulnerability for the vendor-released patched version once available. If immediate upgrade is not possible, deactivate the JetSmartFilters plugin (note: this will break all dependent filter widgets and product/post catalog filtering on the frontend) or place a WAF rule in front of WordPress that blocks SQL metacharacters and UNION/SLEEP/BENCHMARK patterns on admin-ajax.php actions and REST routes belonging to jet-smart-filters (trade-off: aggressive rules can break legitimate filter AJAX requests that use commas, brackets, or comparison operators). Rotate all WordPress secrets in wp-config.php and force a password reset for all users if there is any evidence of exploitation, since unauthenticated database read is sufficient to extract wp_users hashes.
