Synopsis

The remote host is missing a security update.

Description

The version of Mattermost Server installed on the remote host is prior to 10.4.4 / 10.3.4 / 9.11.9 / 10.5.1. It is, therefore, affected by a vulnerability as referenced in the MMSA-2025-00432 advisory.

 - Mattermost versions 10.4.x <= 10.4.2, 10.3.x <= 10.3.3, 9.11.x <= 9.11.8, 10.5.x <= 10.5.0 fail to restrict bookmark creation and updates in archived channels, which allows authenticated users created or update bookmarked in archived channels (CVE-2025-24920)

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 Mattermost Server version 10.4.3 / 10.3.4 / 9.11.9 / 10.5.1 or later.
