Detailsinfo

A vulnerability was found in egoi Smart Marketing SMS and Newsletters Forms Plugin up to 5.1.24 and classified as critical. Affected by this issue is the function get_option. The manipulation of the argument Name with an unknown input leads to a sql injection vulnerability. Using CWE to declare the problem leads to CWE-89. The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Impacted is confidentiality, integrity, and availability. CVE summarizes:

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.

The advisory is available at wordfence.com. This vulnerability is handled as CVE-2026-77161 since 08/20/2026. The exploitation is known to be easy. The attack may be launched remotely. Technical details are known, but there is no available exploit. The structure of the vulnerability defines a possible price range of USD $0-$5k at the moment (estimation calculated on 09/12/2026). This vulnerability is assigned to T1505 by the MITRE ATT&CK project.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
