Details
As written in the advisory (Markdown source, shown as plain text).
One of the API in Mattermost version 6.4.1 and earlier fails to properly protect the permissions, which allows the authenticated members with restricted custom admin role to bypass the restrictions and view the server logs and server config.json file contents. Per the Mattermost security updates page, versions 6.4.2, 6.3.5, 6.2.5, and 5.37.9 contain patches for this issue
