- CVE-2026-19800, 9 Sep 2026
- 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, 5 Sep 2026
- 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 record
- CVE-2026-12918, 10 Jul 2026
- 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 record
- CVE-2026-14342, 9 Jul 2026
- 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. CVE record
- CVE-2026-2025, 4 Mar 2026
- The Mail Mint WordPress plugin before 1.19.5 does not have authorization in one of its REST API endpoint, allowing unauthenticated users to call it and retrieve the email addresses of users on the blog CVE record
- CVE-2026-1258, 14 Feb 2026
- 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 record
- CVE-2026-1447, 3 Feb 2026
- 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. CVE record
- CVE-2025-11967, 8 Nov 2025
- The Mail Mint plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the process_contact_attribute_import function in all versions up to, and including, 1.18.10. This makes it possible for authenticated attackers, with Administrator-level access and above, to upload arbitrary files on the affected site's server which may make remote code execution possible. CVE record
What to do if you run Mail Mint
If you run Mail Mint, open WordPress and check the installed version in Plugins. Compare it with the affected versions in the vulnerability record. If a fixed version is available, take a current backup and update to that version or the latest supported release.
If no fixed version exists, consider disabling and removing the plugin or replacing it with a maintained alternative. After dealing with the affected software, check administrator users, unexpected file changes, redirects, unfamiliar pages and security logs for signs that the site may already have been altered.
