CVE-2025-3430: 3DPrint Lite WordPress Plugin SQLi Vulnerability

CVE-2025-3430 Overview

CVE-2025-3430 is a SQL Injection vulnerability in the 3DPrint Lite plugin for WordPress, affecting all versions up to and including 2.1.3.6. The flaw resides in the handling of the printer_text parameter, which is passed into a SQL query without sufficient escaping or parameterization. Attackers with high privileges can append additional SQL statements to existing queries and extract sensitive data from the WordPress database. The vulnerability is classified under [CWE-89] (Improper Neutralization of Special Elements used in an SQL Command). The vendor, wp3dprinting, released a patched version via the WordPress plugin repository.

Critical Impact
Authenticated attackers can inject SQL statements through the printer_text parameter to read sensitive database contents, including user credentials and configuration data.

Affected Products

wp3dprinting 3DPrint Lite plugin for WordPress
All versions up to and including 2.1.3.6
WordPress sites running the vulnerable plugin on any hosting environment

Technical Details for CVE-2025-3430

Vulnerability Analysis

The 3DPrint Lite plugin exposes functionality that incorporates the printer_text parameter directly into a SQL query. The plugin fails to escape user-supplied input and does not use prepared statements with bound parameters. Attackers can supply crafted input that breaks out of the intended query context and appends arbitrary SQL clauses. The appended clauses execute within the plugin's existing database session, inheriting its privileges against the WordPress database.

Successful exploitation enables data extraction from any table the WordPress database user can read. This commonly includes the wp_users table containing password hashes, the wp_usermeta table, and site configuration stored in wp_options. The vulnerability does not require user interaction and is exploitable remotely over the network.

Root Cause

The root cause is insufficient input neutralization combined with unsafe SQL construction. The plugin concatenates the printer_text request parameter into a SQL statement rather than using $wpdb->prepare() with placeholders. WordPress provides sanitization helpers such as esc_sql() and parameterized query APIs, but the vulnerable code paths bypass these protections.

Attack Vector

Exploitation requires network access to the WordPress site and an authenticated session with elevated privileges, as reflected by the CVSS vector requiring high privileges. An authenticated attacker sends an HTTP request to the vulnerable endpoint with a malicious printer_text value containing SQL metacharacters. The injected payload modifies the executed query to return attacker-controlled data, typically through UNION-based or boolean-based extraction techniques.

The vulnerability manifests in the plugin's parameter handling logic. See the Wordfence Vulnerability Report for technical details on the vulnerable code path.

Detection Methods for CVE-2025-3430

Indicators of Compromise

HTTP POST or GET requests to 3DPrint Lite plugin endpoints containing SQL metacharacters such as UNION SELECT, --, ';, or encoded variants in the printer_text parameter
Unusual database query errors in PHP error logs referencing the plugin's SQL statements
Unexpected outbound data patterns from the WordPress host following requests to plugin endpoints
Access log entries showing authenticated requests to plugin URLs from unexpected IP addresses or user agents

Detection Strategies

Inspect web server access logs for requests to 3DPrint Lite plugin endpoints containing SQL injection patterns in the printer_text parameter
Deploy web application firewall (WAF) rules targeting SQLi payloads directed at WordPress plugin paths
Monitor database query logs for anomalous UNION, SLEEP, or INFORMATION_SCHEMA references originating from plugin queries
Correlate authenticated session activity with database read spikes against wp_users and wp_options

Monitoring Recommendations

Enable WordPress debug logging and forward PHP error output to a central logging platform
Alert on any 3DPrint Lite requests from accounts not expected to use printer configuration features
Baseline normal query volume for the WordPress database user and alert on deviations
Review user role assignments to identify unnecessary privileged accounts that could exploit the issue

How to Mitigate CVE-2025-3430

Immediate Actions Required

Update the 3DPrint Lite plugin to the version released after changeset 3249784 published in the WordPress plugin repository
Audit WordPress user accounts and revoke elevated privileges from accounts that do not require them
Rotate credentials for all administrative accounts if exploitation is suspected
Review database contents for signs of unauthorized access, including recent reads against wp_users

Patch Information

The vendor addressed the vulnerability in a release tracked by the WordPress Plugin Change Log. Site operators should upgrade through the WordPress admin plugin manager or by replacing the plugin directory with the fixed release. Verify the installed version is newer than 2.1.3.6 after the update.

Workarounds

Deactivate and remove the 3DPrint Lite plugin until the patched version can be applied
Restrict access to WordPress administrative endpoints using IP allowlists at the web server or WAF layer
Deploy generic SQL injection filtering rules in a WAF to block common payloads targeting WordPress plugins
Apply the principle of least privilege to the database user configured in wp-config.php, limiting it to the minimum required grants

bash

# Example WP-CLI commands to update the plugin and verify the installed version
wp plugin update 3dprint-lite
wp plugin get 3dprint-lite --field=version
