CVE-2026-42774
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedImproper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in Crocoblock JetEngine allows SQL Injection. This issue affects JetEngine: from n/a through 3.8.8.1.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceSQL Injection vulnerability in Crocoblock JetEngine plugin allows attackers to inject malicious SQL commands through unsanitized input. The vulnerability exists in the plugin's database query handling, potentially allowing unauthorized data access, modification, or deletion.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Verify JetEngine plugin is installedNavigate to WordPress admin dashboard > Plugins > Installed Plugins. Look for 'JetEngine' in the plugin list. Note whether it is activated or deactivated.Affected if JetEngine plugin is installed and activated - the vulnerability only applies to active installations
-
Determine installed JetEngine versionIn the Plugins list, find JetEngine and locate the version number displayed below the plugin name. Alternatively, check the plugin file header at /wp-content/plugins/jetengine/jetengine.php for the 'Version' constant.Affected if The installed version is unknown, unpatched, or falls within any vulnerable version range for this CVE
-
Identify exposed user input fieldsReview JetEngine settings for any Dynamic Field, Dynamic Text, or Query Builder elements that accept user input. Check JetEngine > Dynamic Settings and any Custom Post Type/Post Type setups that use JetEngine meta boxes.Affected if User-facing forms, search fields, or filter elements built with JetEngine are present and accept unsanitized input that gets passed to database queries
-
Inspect database query execution pointsExamine JetEngine's PHP files in /wp-content/plugins/jetengine/includes/ for direct DB:query(), $wpdb->prepare(), or raw SQL execution that references $_GET, $_POST, or $_REQUEST superglobals without sanitization.Affected if Custom code or JetEngine Dynamic Forms are configured to pass user input directly into SQL queries without using prepared statements or escaping functions
-
Check for custom code modificationsLook in WordPress theme functions.php or any custom JetEngine add-ons for code that hooks into jet_engine hooks (e.g., jet_engine_after_save_meta, jet_engine_booking_data) and processes user-submitted data.Affected if Custom code exists that processes JetEngine form submissions or query builder parameters without input validation
A user is affected if JetEngine is active with an unpatched version AND user input fields (forms, filters, dynamic queries) are configured that pass unsanitized data directly into SQL queries.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpdate JetEngine to the latest patched version beyond 3.8.8.1. Review and sanitize all user-supplied input in database queries, and implement prepared statements using WordPress WPDB methods.
