SQL Injection in Mail Mint WordPress Plugin

Publication date: 2026-10-16

Last updated on: 2026-10-16

Assigner: Wordfence

Description
The Mail Mint plugin for WordPress is vulnerable to SQL Injection via the 'filters' parameter of the /wp-json/mrm/v1/segments/contacts REST endpoint in versions up to, and including, 1.31.4 This is due to insufficient escaping on the user supplied filter 'value' before it is appended to a SQL query in SegmentFilterService::get_meta_join_query() at line 797, where the value is string-interpolated into the WHERE fragment in a numeric (unquoted) context and the surrounding $wpdb->prepare() calls do not cover the injected value. This makes it possible for authenticated attackers, with the custom 'mint_read_contacts' capability (granted to Administrators by default, and configurable to lower roles via the plugin's role manager), to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

CWE ID Description
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. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.

Executive Summary

This vulnerability is a SQL Injection flaw in the Mail Mint WordPress plugin. It allows authenticated attackers with specific capabilities to inject malicious SQL queries via the 'filters' parameter in a REST endpoint. The issue occurs due to improper escaping of user-supplied input, which is then used in a SQL query without proper sanitization.

Impact Analysis

An attacker could exploit this to extract sensitive data from the database, such as user credentials, personal information, or other confidential data. The attack requires authenticated access with the 'mint_read_contacts' capability, which is granted to administrators by default.

Compliance Impact

This vulnerability could lead to unauthorized access and exposure of personal data, violating GDPR and HIPAA requirements for data protection and confidentiality. Organizations using this plugin may face compliance violations and potential legal consequences.

Mitigation Strategies

Update the Mail Mint plugin for WordPress to the latest version, which patches the SQL injection vulnerability in the 'filters' parameter of the REST endpoint. If immediate update is not possible, disable the plugin until patched.
