CVE-2026-18702Network attack vector

Authenticated server-wide logging modification via profile authorization bypass

Published Aug 11, 2026 · Updated Aug 11, 2026

Improper authorization in MongoDB Server allows remote authenticated users to alter server-wide diagnostic logging through the profile command. The command accepts database-scoped privileges but applies slowms, sampleRate, or filter changes to the entire server in affected 7.0, 8.0, and 8.3 releases. A limited database user can suppress useful records or generate excessive log volume, obscuring activity and degrading operational monitoring.
