Mail Mint vulnerabilities

Unauthenticated PHP Object Injection vulnerability in Mail Mint versions up to 1.31.0. An attacker can inject malicious PHP objects, potentially leading to arbitrary code execution.

The Mail Mint plugin for WordPress in versions up to and including 1.31.4 is vulnerable to SQL Injection via the 'filters' parameter of the /wp-json/mrm/v1/segments/contacts REST endpoint. Insufficient escaping of the user-supplied filter 'value' before it is appended to a SQL query in SegmentFilterService::get_meta_join_query() at line 797 — 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.

The Mail Mint plugin for WordPress is vulnerable to SQL Injection via the 'status' parameter in all versions up to 1.31.0. Authenticated attackers with administrator-level access can append SQL queries to extract sensitive information. The vulnerability is due to insufficient query preparation and JSON parsing bypassing WordPress protections.

The Mail Mint plugin versions up to 1.31.0 contain an unauthenticated broken access control vulnerability. This allows unauthorized access to protected features.

The Mail Mint plugin for WordPress is vulnerable to generic SQL injection via the 'recipients' parameter in all versions up to and including 1.24.1. Authenticated attackers with administrator-level access can store a malicious payload that is later executed when reading campaigns, allowing extraction of sensitive database information.

The Mail Mint plugin for WordPress is vulnerable to time-based SQL Injection via the 'contact_ids' parameter in versions up to and including 1.24.2. This is due to insufficient escaping and lack of proper SQL query preparation.

The WordPress plugin Mail Mint up to version 1.19.5 exposes sensitive system information to unauthorized entities, allowing retrieval of embedded sensitive data.
