Go to dashboardThe Mail Mint WordPress plugin up to and including 1.31.4 fails to escape a filter value in its contacts segment REST endpoint, so it is concatenated into an SQL query. An authenticated user with the mint_read_contacts capability can inject SQL to extract sensitive data from the site database.

Sites running Mail Mint at version 1.31.4 or earlier. Exposure requires a logged-in account holding the mint_read_contacts capability, which Administrators have by default and which the plugin's role manager can extend to lower roles. Sites where only trusted administrators hold that capability face lower practical risk, and sites not running Mail Mint can skip it.

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.
