CVE-2026-3018

The Newsletters plugin for WordPress is vulnerable to time-based SQL Injection via the ‘wpmlsubscriber_id’ parameter in all versions up to, and including, 4.13 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

Summary		(es) El plugin Newsletters para WordPress es vulnerable a inyección SQL basada en tiempo a través del parámetro 'wpmlsubscriber_id' en todas las versiones hasta la 4.13, inclusive, debido a un escape insuficiente en el parámetro proporcionado por el usuario y a la falta de preparación suficiente en la consulta SQL existente. Esto permite a atacantes no autenticados añadir consultas SQL adicionales a consultas ya existentes que pueden utilizarse para extraer información sensible de la base de datos.
