Synopsis

The remote host is missing one or more security updates.

Description

The version of Mattermost Server installed on the remote host is prior to 9.11.13, 10.5.4, or 10.7.1. It is, therefore, affected by multiple vulnerabilities as referenced in the MMSA-2025-00457 and MMSA-2025-00462 advisories.

 - Mattermost versions 10.7.x <= 10.7.0, 10.5.x <= 10.5.3, 9.11.x <= 9.11.12 fail to properly enforce access controls for guest users accessing channel member information, allowing authenticated guest users to view metadata about members of public channels via the channel members API endpoint. (CVE-2025-1792)

 - Mattermost versions 10.7.x <= 10.7.0, 10.5.x <= 10.5.3, 9.11.x <= 9.11.12 fail to properly enforce access control restrictions for System Manager roles, allowing authenticated users with System Manager privileges to view team details they should not have access to via direct API requests to team endpoints, even when explicitly configured with 'No access' to Teams in the System Console. (CVE-2025-3611)

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 Mattermost Server version 9.11.13 / 10.5.4 / 10.7.1 or later.
