CVE-2025-3427 Overview
CVE-2025-3427 is a SQL Injection vulnerability in the 3DPrint Lite plugin for WordPress. The flaw exists in the handling of the infill_text parameter across all versions up to and including 2.1.3.6. The plugin fails to properly escape user-supplied input and does not use prepared statements for the affected SQL query. An authenticated attacker with high privileges can append arbitrary SQL to existing queries and extract sensitive database content. The issue is tracked under CWE-89 (Improper Neutralization of Special Elements used in an SQL Command).
Critical Impact
Attackers can inject arbitrary SQL through the infill_text parameter to read sensitive data from the WordPress database, including user records and configuration secrets.
Affected Products
- wp3dprinting/3dprint_lite WordPress plugin, all versions up to and including 2.1.3.6
- WordPress sites running the 3DPrint Lite plugin without the patched release
- Environments where privileged users can submit the infill_text parameter

Technical Details for CVE-2025-3427
Vulnerability Analysis
The 3DPrint Lite plugin accepts a user-controlled infill_text parameter and concatenates it into a SQL query without adequate escaping or parameter binding. Because the query is not fully prepared with placeholders, attacker-controlled characters alter query structure. The result is a classic in-band SQL injection against the WordPress database layer. Exploitation requires authenticated access with elevated privileges, which constrains opportunistic abuse but does not eliminate risk from compromised accounts or malicious insiders. Successful injection yields confidentiality impact against the database, including post content, user metadata, and plugin configuration.
Root Cause
The underlying defect is improper neutralization of special characters in a SQL statement [CWE-89]. The plugin interpolates infill_text directly into the query string rather than binding it through $wpdb->prepare() with typed placeholders such as %s. Any single quote, comment token, or UNION clause supplied by the attacker is passed through to the database.
Attack Vector
The attack is delivered over the network through the plugin's request handler that processes the infill_text field. A privileged authenticated user submits a crafted value containing SQL syntax. The injected clause is appended to the legitimate query and executed by the WordPress database driver. See the Wordfence Vulnerability Analysis for additional technical context.

Detection Methods for CVE-2025-3427
Indicators of Compromise
- Requests to 3DPrint Lite plugin endpoints containing SQL metacharacters in the infill_text parameter, such as single quotes, UNION SELECT, --, or /* sequences.
- Unexpected database errors in PHP error logs referencing the plugin's query path.
- Anomalous reads from wp_users or wp_options correlated with authenticated plugin activity.
Detection Strategies
- Deploy web application firewall signatures that inspect the infill_text parameter for SQL syntax tokens.
- Review access logs for POST requests to 3DPrint Lite handlers that contain encoded SQL payloads.
- Enable MySQL general query or slow query logging on affected hosts and alert on queries containing UNION, SLEEP, or INFORMATION_SCHEMA originating from plugin code paths.
Monitoring Recommendations
- Monitor privileged WordPress account activity for unexpected form submissions involving 3DPrint Lite.
- Alert on authentication from new IP addresses to administrator and editor accounts that have access to the plugin.
- Track plugin version inventory across WordPress fleets to confirm all instances are at or above the patched release.
How to Mitigate CVE-2025-3427
Immediate Actions Required
- Update the 3DPrint Lite plugin to a version later than 2.1.3.6 as soon as the vendor-patched release is available.
- Audit WordPress administrator, editor, and contributor accounts and rotate credentials for any high-privilege users.
- Review database query logs for prior injection attempts against the infill_text parameter.
Patch Information
The vendor committed a code change tracked in the WordPress plugin repository. See the WordPress Changeset Update for the exact modifications. Administrators should install the fixed release through the WordPress plugin updater and verify the installed version in the plugin dashboard.
Workarounds
- Deactivate the 3DPrint Lite plugin until the patched version can be installed.
- Restrict access to the plugin's request handlers at the web server or WAF layer, blocking SQL metacharacters in the infill_text parameter.
- Reduce the number of high-privilege WordPress accounts and enforce multi-factor authentication for all remaining administrators.
# Example WAF rule concept to block SQL tokens in the vulnerable parameter
# Adapt to your WAF syntax (ModSecurity shown for illustration)
