CVE-2026-13076

An authenticated user can cause a {{mongod}} process to be terminated by the operating system under memory pressure by performing a specific data type conversion operation within MongoDB's aggregation framework. The behavior stems from disproportionate memory consumption during this operation, and requires both write access to the database and the ability to run aggregation queries.

Summary		(es) Un usuario autenticado puede provocar que un proceso {{mongod}} sea terminado por el sistema operativo bajo presión de memoria al realizar una operación específica de conversión de tipo de datos dentro del framework de agregación de MongoDB. El comportamiento se deriva de un consumo de memoria desproporcionado durante esta operación, y requiere tanto acceso de escritura a la base de datos como la capacidad de ejecutar consultas de agregación.
