CVE-2026-18702 PUBLISHED

Improper Authorization in MongoDB profile Command Allows Unauthorized Modification of Server-Wide Diagnostic Settings

Assigner: mongodb
Reserved: 03.08.2026 Published: 11.08.2026 Updated: 11.08.2026

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.
