CVE-2026-14238: VitePOS WordPress Plugin SQLi Vulnerability

CVE-2026-14238 Overview

CVE-2026-14238 is a SQL injection vulnerability in the vitepos WordPress plugin versions prior to 3.6.0. The plugin fails to sanitize or parameterize an identifier taken from a REST request body before using it in a database query within one of its report endpoints. An authenticated user with administrator-level access can inject arbitrary SQL through this endpoint. The issue is tracked under CWE-89 (Improper Neutralization of Special Elements used in an SQL Command).

Critical Impact
Administrator accounts can execute arbitrary SQL queries against the WordPress database, enabling data extraction from the underlying database backend.

Affected Products

vitepos WordPress plugin versions prior to 3.6.0
WordPress sites running the affected plugin with REST API report endpoints exposed
Multi-site or hosted environments where administrator access spans tenant boundaries

Technical Details for CVE-2026-14238

Vulnerability Analysis

The vitepos plugin exposes REST API endpoints used to generate reports from point-of-sale data. One of these report endpoints reads an identifier field directly from the REST request body and concatenates it into a SQL query. Because the value is treated as a raw identifier rather than a bound parameter, the query executes attacker-supplied SQL fragments.

Exploitation requires an authenticated session with administrator privileges, which limits the population of attackers who can trigger the flaw. On sites with delegated administrators, subsite admins, or environments where administrator accounts are shared across roles, the trust boundary is meaningful. The scope change reflected in the CVSS metrics indicates the injection reaches the database engine beyond the plugin's own logical boundary.

Root Cause

The root cause is missing input handling on an identifier value taken from a REST request body. Identifiers such as column or table names cannot be bound using standard $wpdb->prepare() placeholders and must be validated against an allowlist. The plugin performs neither sanitization nor allowlisting before interpolating the value into the SQL statement.

Attack Vector

An attacker with a valid administrator session sends a crafted POST request to the affected report REST route. The malicious identifier field carries SQL fragments that break out of the intended context and append attacker-controlled clauses. Because the query runs with WordPress database privileges, the attacker can read data from tables outside the plugin's schema, including wp_users and wp_usermeta.

No public proof-of-concept, exploit code, or CISA KEV listing is currently associated with this CVE. See the WPScan Vulnerability Report for the technical write-up.

Detection Methods for CVE-2026-14238

Indicators of Compromise

REST API POST requests to vitepos report endpoints containing SQL metacharacters such as single quotes, UNION, SELECT, --, or /* in identifier fields
Unexpected database errors in debug.log or PHP error logs referencing the vitepos plugin
Anomalous read activity against wp_users, wp_usermeta, or wp_options tables originating from PHP-FPM processes
New or modified administrator accounts following report endpoint activity

Detection Strategies

Enable WordPress REST API request logging and inspect payloads sent to vitepos report routes
Deploy a web application firewall rule that inspects JSON bodies for SQL syntax within identifier-shaped parameters
Correlate authenticated administrator session activity with database error spikes
Review MySQL general query log entries for statements referencing plugin tables with unusual clause structures

Monitoring Recommendations

Alert on any REST call to vitepos report endpoints from IP addresses outside the administrator allowlist
Track administrator login events and correlate against report endpoint invocations from the same session
Monitor for schema enumeration queries such as reads against information_schema.tables from the WordPress database user

How to Mitigate CVE-2026-14238

Immediate Actions Required

Update the vitepos plugin to version 3.6.0 or later on all WordPress installations
Audit the administrator role membership and remove accounts that do not require full privileges
Rotate credentials and application passwords for any administrator account that may have been compromised
Review database audit logs for evidence of unauthorized SELECT activity against sensitive tables

Patch Information

The vendor addressed the issue in vitepos version 3.6.0 by parameterizing or allowlisting the identifier consumed by the report REST endpoint. Refer to the WPScan Vulnerability Report for the fix reference and confirm the deployed version reports 3.6.0 or higher through the WordPress admin plugin screen.

Workarounds

Restrict access to /wp-json/ report routes at the reverse proxy or WAF layer until the plugin is updated
Enforce two-factor authentication on all administrator accounts to reduce the risk of session takeover
Apply the principle of least privilege by using the Editor or Shop Manager role where administrator access is not required

bash

# Verify installed plugin version and update via WP-CLI
wp plugin get vitepos --field=version
wp plugin update vitepos --version=3.6.0
wp plugin list --status=active --format=table
