CVE-2026-18702

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

State: Published
Severity: 5.3 Medium
Published: Aug 11, 2026
Updated: Aug 11, 2026
Reserved: Aug 3, 2026

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.
