CVE-2026-13063

An authenticated user with standard read/write privileges can cause the mongod process to terminate due to an out-of-memory condition by sending a crafted aggregation command. MongoDB's libmongocrypt library insufficiently validates payload-supplied values, which can result in an excessively large memory allocation.

Summary		(es) Un usuario autenticado con privilegios estándar de lectura/escritura puede provocar la terminación del proceso mongod debido a una condición de agotamiento de memoria al enviar un comando de agregación manipulado. La biblioteca libmongocrypt de MongoDB valida insuficientemente los valores proporcionados en la carga útil, lo que puede resultar en una asignación de memoria excesivamente grande.
