CVE-2026-18702
Full vulnerability record from the local CVENow database.
Description
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.

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."
