"The version of MongoDB installed on the remote host is 8.0.x prior to 8.0.28. It is, therefore, affected by a
vulnerability:

  - An authenticated user with read-only privileges can cause the mongod process to terminate abnormally by
    issuing a crafted aggregation command, resulting in denial of service for all connected clients until the
    process is restarted. The issue stems from an internal engine selection inconsistency triggered by a
    specific combination of aggregation options. (CVE-2026-13073)

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