CVE-2026-18702

An issue in MongoDB Server could allow an authenticated user with limited, database-scoped privileges to modify diagnostic logging settings that affect the entire server rather than just the intended database. This could allow suppression of diagnostic logging server-wide, potentially obscuring unauthorized activity, or degrade operational monitoring by causing excessive log volume.

Summary		(es) Un problema en el servidor MongoDB podría permitir a un usuario autenticado con privilegios limitados y con alcance a la base de datos modificar la configuración de registro de diagnóstico que afecta a todo el servidor en lugar de solo a la base de datos prevista. Esto podría permitir la supresión del registro de diagnóstico en todo el servidor, ocultando potencialmente actividad no autorizada, o degradar la monitorización operativa al causar un volumen excesivo de registros.
