Summary
CVE-2026-56068 is a critical unauthenticated SQL injection vulnerability in the JetEngine WordPress plugin by Crocoblock (Jetimpex Inc.), affecting all versions up to and including 3.8.10.2. The flaw falls under CWE-89 (Improper Neutralization of Special Elements Used in an SQL Command) and carries a CVSS v3.1 base score of 9.3 (Critical), enabling any unauthenticated remote attacker to directly interact with the underlying WordPress database and exfiltrate sensitive data.
Technical details
- Root cause: Insufficient sanitization and improper neutralization of user-supplied input in SQL query construction, classified as CWE-89. This allows an attacker to inject arbitrary SQL statements into the database layer without authentication.
- Trigger conditions: No authentication, account, or user interaction is required. Attack complexity is low, meaning exploitation does not depend on special conditions or race conditions — any unauthenticated HTTP request can trigger the vulnerability.
- Attack vector: Network-accessible; exploitable remotely over the internet via standard HTTP/HTTPS requests against an exposed WordPress site running the vulnerable plugin.
- Impact: Successful exploitation allows an attacker to directly query the WordPress database. This includes the ability to extract sensitive records such as hashed user credentials, email addresses, session tokens, and any other data stored in the database. The Changed scope (S:C) indicates the vulnerability can affect resources beyond the plugin’s immediate security boundary. Confidentiality impact is High (C:H); Availability impact is Low (A:L); Integrity impact is None (I:N).
- No public proof-of-concept (PoC) has been confirmed at time of publication (June 26, 2026).
Affected software
- JetEngine WordPress Plugin by Crocoblock (Jetimpex Inc.) — all versions ≤ 3.8.10.2
Severity
- CVSS v3.1 Base Score: 9.3 (Critical)
- Vector String:
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:L
Mitigation and recommended actions
- Immediate action: Update JetEngine to version 3.8.11 or later, which contains the vendor-provided fix. Administrators should verify the installed plugin version in the WordPress dashboard under Plugins → Installed Plugins and apply the update without delay.
- If immediate patching is not possible: Restrict access to the WordPress site at the network or WAF level to reduce exposure. Consider temporarily disabling the JetEngine plugin until the update can be applied.
- Ongoing hygiene: Enable automatic plugin updates for security releases where operationally feasible to minimize the window of exposure for future vulnerabilities.
