What is CVE-2026-13074?

A vulnerability exists in MongoDB Server that allows unauthenticated remote clients to trigger excessive CPU consumption. By sending a specific combination of parameters to the awaitable hello command in exhaust mode, the server may enter a response loop that circumvents normal throttling mechanisms. This condition can lead to degraded server performance and availability, posing a significant risk to applications relying on MongoDB for their operations.
