CVE-2026-77161

Smart Marketing SMS and Newsletters Forms <= 5.1.24 - Authenticated (Subscriber+) SQL Injection via Parameter Name

Published Sep 12, 2026 CVSS 3.1 · 6.5 Medium EPSS < 1% KEV · Not listed

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.

Analysis

Technical impact

The Smart Marketing SMS and Newsletters Forms plugin for WordPress contains a classic SQL Injection flaw (CWE-89) that allows authenticated users with subscriber-level or higher privileges to craft specially named parameters that inject additional SQL statements into existing database queries. This unescaped injection can be used to extract arbitrary data from the site's database, leading to confidential data exposure.

Affected Systems

All releases of the egoi Smart Marketing SMS and Newsletters Forms plugin with a version number of 5.1.24 or lower are impacted. The flaw is active only when the['enabled'] is true) and the get_option('egoi_mapping') value is truthy,.

Risk and Exploitability

The CVSS score of 6.5 indicates moderate severity, while the EPSS score of less than 1% shows a low current exploitation probability. The vulnerability is not listed in the CISA KEV catalog. An attacker would need authenticated access with at least subscriber-level privileges and the sync feature enabled to inject and execute additional SQL queries, making the practical risk limited by the specific configuration and authentication requirements.
