CVE-2026-13074 · Awaitable Hello Command in Exhaust Mode Unthrottled Response Loop Leading to Denial of Service

This page contains facts from public vulnerability sources. Check the original advisory before updating.

An unauthenticated remote client can cause excessive CPU consumption on a MongoDB server by sending a specific combination of parameters to the awaitable hello command in exhaust mode. The server's handling of this combination results in a response loop that bypasses normal throttling, allowing a small number of connections to degrade server availability.
