MongoDB 8.0.x < 8.0.24 DoS

high Nessus Plugin ID 320793

Synopsis

The remote host is missing a security update.

Description

The version of MongoDB installed on the remote host is 8.0.x prior to 8.0.24. It is, therefore, affected by a denial of service vulnerability:

 - In Vulnerable MongoDB Server versions, an aggregation stage can leave its _subPipeline field null during processing of certain pipelines. If a getMore is subsequently issued on the same cursor, the server may dereference this null sub-pipeline when reattaching to the operation context, accessing an invalid address and crashing the process. This issue allows an authenticated user who can run aggregation pipelines to cause a denial of service by issuing a specially crafted aggregation followed by getMore on affected versions. (CVE-2026-9743)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to MongoDB version 8.0.24 or later.
