# CVE-2026-12360: JetEngine \<= 3.8.10.1 - Unauthenticated SQL Injection via Listing Grid Load More AJAX Endpoint

- Severity: CVSS 7.5 (High), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N
- CISA SSVC: exploitation=none, automatable=yes, technicalImpact=partial
- Known exploited (CISA KEV): no
- Published: 2026-06-17 · Updated: 2026-06-17

## Affected

- Crocoblock JetEngine: through 3.8.10.1

## Description

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.
