"The version of Mattermost Server installed on the remote host is prior to 9.5.9 or 9.11.1. It is, therefore, affected by
a vulnerability as referenced in the MMSA-2024-00373 advisory.

  - Mattermost versions 9.11.x <= 9.11.0 and 9.5.x <= 9.5.8 fail to validate that the message of the permalink
    post is a string, which allows an attacker to send a non-string value as the message of a permalink post
    and crash the frontend. (CVE-2024-47003)

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