CVE-2026-14342

Mail Mint <= 1.24.2 - Authenticated (Administrator+) SQL Injection via 'contact_ids' Parameter

The Mail Mint – Email Marketing, Newsletter, Email Automation & WooCommerce Emails plugin for WordPress is vulnerable to time-based SQL Injection via the 'contact_ids' parameter in all versions up to, and including, 1.24.2 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 administrator-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

Mail Mint <= 1.24.1 - Authenticated (Administrator+) SQL Injection via 'recipients' Parameter

The Mail Mint – Email Marketing, Newsletter, Email Automation & WooCommerce Emails plugin for WordPress is vulnerable to generic SQL Injection via the 'recipients' parameter in all versions up to, and including, 1.24.1 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 administrator-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. This is a second-order SQL injection: the malicious payload is first stored unsanitized via a POST request to /mrm/v1/campaigns/ (bypassing filter_recipients() validation because an int-cast of a string like '1) OR ...' evaluates to a real numeric ID), and is then triggered by a subsequent GET request to /mrm/v1/campaigns/{id} that deserializes the recipients and passes the raw id string through array_column() into the vulnerable query.

CVE-2026-19800

Mail Mint <= 1.31.0 - Authenticated (Custom+) SQL Injection via 'status' Parameter

The Mail Mint – Email Marketing, Newsletter, Email Automation & WooCommerce Emails plugin for WordPress is vulnerable to SQL Injection via the 'status' parameter in all versions up to, and including, 1.31.0 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. The $wpdb->prepare() call does not protect against this injection because the attacker-controlled $contact_filter_query fragment is concatenated into the SQL format string before prepare() executes — prepare() only processes %s/%d placeholders and cannot sanitize content already embedded in the format string. REST API JSON bodies are parsed from php://input and bypass WordPress's wp_magic_quotes(), meaning double-quote characters in status array values reach the SQL sink unescaped. This makes it possible for authenticated attackers, with administrator-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. The required 'mint_read_contacts' capability is a plugin-specific capability not assigned to any default WordPress role; it must be explicitly granted by an administrator, making this effectively an Administrator+ vulnerability.

CVE-2026-10196

Mail Mint <= 1.31.0 - Unauthenticated PHP Object Injection in Arbitrary Form Fields

The Mail Mint – Email Marketing, Newsletter, Email Automation & WooCommerce Emails plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 1.31.0 via deserialization of untrusted input in the 'handle_form_submission' function. This makes it possible for unauthenticated attackers to inject a PHP Object. The additional presence of a POP chain allows attackers to execute code on the server. The vulnerability was partially patched in version 1.23.1.

CVE-2026-1258

Mail Mint <= 1.19.2 - Authenticated (Administrator+) SQL Injection via Multiple API Endpoints

The Mail Mint plugin for WordPress is vulnerable to blind SQL Injection via the 'forms', 'automation', 'email/templates', and 'contacts/import/tutorlms/map' API endpoints in all versions up to, and including, 1.19.2 . This is due to insufficient escaping on the user supplied 'order-by', 'order-type', and 'selectedCourses' parameters and lack of sufficient preparation on the existing SQL queries. This makes it possible for authenticated attackers, with administrator level access and above, to append additional SQL queries into already existing queries.

CVE-2026-1447

Mail Mint <= 1.19.2 - Cross-Site Request Forgery to Stored Cross-Site Scripting

The Mail Mint plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.19.2. This is due to missing nonce validation on the create_or_update_note function. This makes it possible for unauthenticated attackers to create or update contact notes via a forged request granted they can trick a site administrator into performing an action such as clicking on a link. Due to missing sanitization and escaping this can lead to stored Cross-Site Scripting.
