At a glance

CVE-2024-35736 is a critical-severity Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in the Visualizer WordPress plugin, affecting versions <= 3.11.1. It carries a CVSS score of 9.9 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires an authenticated account at Subscriber level or above. The issue is fixed in version 3.11.2; sites on affected versions should update now. Disclosed June 2024, reported by Trương Hữu Phúc (truonghuuphuc).

Vulnerability Overview

The Visualizer: Tables and Charts Manager for WordPress plugin for WordPress is vulnerable to SQL Injection via the saveQuery function() in all versions up to, and including, 3.11.1 due to a missing capability check on a function that runs SQL Queries. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no interaction from a victim user. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.

CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')

Visualizer <= 3.11.1 carries this weakness at function(), and reaching it takes an account at Subscriber level or above. SQL injection happens when request data is concatenated into a query instead of being bound as a parameter, letting an attacker change the structure of the statement rather than just its values.

A working injection can read any table the database user can see, which on a WordPress install means user records, password hashes and session or API secrets stored in options. For Visualizer the fix is 3.11.2: builds <= 3.11.1 are affected, anything from 3.11.2 onward is not.

Remediation

Update to version 3.11.2, or a newer patched version

How does WordSec protect against this?

An attacker needs Subscriber access first, so the firewall sees the attempt as traffic from a logged-in account: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Visualizer 3.11.2 closes this, and updating the plugin is the step that ends it.
