CVE-2025-47671: Binary MLM Plan SQLi Vulnerability

CVE-2025-47671 Overview

CVE-2025-47671 is a SQL injection vulnerability in the LETSCMS Binary MLM Plan WordPress plugin (binary-mlm-plan). The flaw affects all plugin versions up to and including 3.0. It stems from improper neutralization of special elements in SQL commands [CWE-89], allowing an authenticated attacker with high privileges to inject arbitrary SQL through vulnerable input parameters.

Critical Impact
An authenticated attacker can extract sensitive database contents, including WordPress user credentials and MLM transaction data, by injecting crafted SQL payloads against the affected plugin.

Affected Products

LETSCMS Binary MLM Plan WordPress plugin versions up to and including 3.0
WordPress installations running the binary-mlm-plan plugin
Sites using LETSCMS MLM Software components dependent on this plugin

Technical Details for CVE-2025-47671

Vulnerability Analysis

The Binary MLM Plan plugin fails to sanitize user-supplied input before incorporating it into SQL queries. An authenticated attacker submits crafted parameters to a vulnerable endpoint, and the plugin concatenates that input directly into a SQL statement executed against the WordPress database.

The vulnerability requires high privileges to exploit, indicating the affected functionality sits behind an administrative or operator-level interface. However, the scope is marked as changed, meaning a successful injection can access data outside the security boundary of the vulnerable component, including the broader WordPress database.

Root Cause

The root cause is the absence of parameterized queries or prepared statements in the plugin's database access layer. User-controlled input flows into SQL query strings without escaping through $wpdb->prepare() or equivalent sanitization functions provided by the WordPress API. This is a classic SQL injection pattern catalogued under [CWE-89].

Attack Vector

An attacker with valid authenticated access at a privileged role sends HTTP requests containing SQL metacharacters in plugin parameters. The plugin embeds these values into a query, and the database executes the attacker-controlled SQL. The attacker can read arbitrary tables, including wp_users and wp_usermeta, exposing password hashes and session tokens.

No public proof-of-concept has been published, and the vulnerability is not listed in CISA KEV. See the Patchstack WordPress Vulnerability Report for additional technical context.

Detection Methods for CVE-2025-47671

Indicators of Compromise

Unusual SQL syntax in HTTP request parameters reaching /wp-admin/ endpoints handled by the binary-mlm-plan plugin, including UNION SELECT, SLEEP(, or comment sequences such as -- and /*.
Unexpected database errors logged by WordPress or MySQL when requests target plugin pages.
Authentication or session activity from privileged accounts originating from unfamiliar IP addresses immediately before suspicious query patterns.

Detection Strategies

Inspect web server access logs for binary-mlm-plan request URIs containing URL-encoded SQL metacharacters such as %27, %20OR%20, or %20UNION%20.
Enable MySQL general query logging in non-production environments to identify queries with concatenated user input referencing MLM tables.
Deploy a web application firewall ruleset that flags SQL injection signatures specifically on plugin endpoints.

Monitoring Recommendations

Alert on privileged WordPress account activity outside business hours or from new geolocations.
Monitor for mass row reads against wp_users, wp_options, or MLM-specific tables from the WordPress database user.
Track plugin file integrity to detect unauthorized modifications following a suspected injection.

How to Mitigate CVE-2025-47671

Immediate Actions Required

Disable or uninstall the binary-mlm-plan plugin until a fixed version is available from LETSCMS.
Audit privileged WordPress accounts and rotate credentials for any account that could access the vulnerable functionality.
Restrict administrative access to the WordPress backend by IP allowlisting where feasible.

Patch Information

As of the last NVD update on 2026-04-23, no fixed version beyond 3.0 has been published in the referenced advisory. Monitor the Patchstack WordPress Vulnerability Report and the LETSCMS vendor channels for patch availability.

Workarounds

Place the WordPress site behind a web application firewall with SQL injection rules enabled for /wp-admin/admin.php and plugin-specific endpoints.
Apply the principle of least privilege by reducing the number of accounts with the elevated role required to reach the vulnerable functionality.
Restrict the MySQL user assigned to WordPress so it cannot read tables outside the WordPress schema, limiting injection blast radius.

bash

# Example: revoke unnecessary privileges from the WordPress MySQL user
REVOKE FILE, SUPER ON *.* FROM 'wp_user'@'localhost';
FLUSH PRIVILEGES;
