MongoDB 8.2.x < 8.2.10 / 8.3.x < 8.3.3 Multiple Vulnerabilities

high Nessus Plugin ID 320795

Language:

Synopsis

The remote host is missing a security update.

Description

The version of MongoDB installed on the remote host is 8.2.x prior to 8.2.10, or 8.3.x prior to 8.3.3. It is, therefore, affected by multiple vulnerabilities:

 - When OIDC authentication is enabled in configuration, clients may set specific values in the 'mechanism' parameter of the 'authenticate' command that lead to server crash. The authenticate command is accessible to unauthenticated clients, leading to pre-auth denial-of-service in affected product configurations.
 (CVE-2026-9742)

 - An authenticated user with the read role may read limited amounts of uninitialized stack memory via specially-crafted issuances of the filemd5 command. (CVE-2026-9754)

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

Solution

Upgrade to MongoDB version 8.2.10 or 8.3.3 or later.
