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.
