Smart Marketing contact mapping exposes subscriber SQL injection

Smart Marketing SMS and Newsletters Forms through 5.1.24 uses an attacker-controlled parameter name in an insufficiently prepared SQL query. A subscriber can append SQL and extract database information when the plugin's sync feature is enabled and egoi_mapping is configured, both ordinary states for contact mapping. The authoritative export does not name the parameter, action, query, or table.

Component: Smart Marketing SMS and Newsletters Forms
Plugin slug: smart-marketing-for-wp
Affected: <= 5.1.24
Safe version: See mitigation notes
Published: Sep 12, 2026
Weakness: CWE-89 — Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')

This CVE was published Sep 12, 2026 and is one of 4 known issues for this plugin.

What to do

Update, patch or deactivate.

No fixed release is confirmed in the authoritative export. Disable the sync feature or deactivate the plugin pending a confirmed fix. The application-level fix must allowlist field names rather than accepting identifiers from the request and must bind all values through prepared queries.

No confirmed safe version is listed. Consider a vendor-supported patch or temporarily restricting the affected functionality while you assess the risk.

Deactivate only when warranted by your risk profile, or when advised by your hosting provider in the limited circumstances where the vulnerability cannot otherwise be mitigated. If you’re unsure which action is appropriate, contact Fused or your hosting provider for guidance.

Source record

Technical description

The Smart Marketing SMS and Newsletters Forms plugin for WordPress is vulnerable to generic SQL Injection via Parameter Name in all versions up to, and including, 5.1.24 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with subscriber-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. Exploitation requires the plugin's sync feature to be enabled (options['enabled']) and get_option('egoi_mapping') to be truthy, both of which reflect ordinary configured states for the plugin's core contact mapping functionality.
