Mattermost version 6.4.x and earlier fails to properly check the plugin version when a plugin is installed from the Marketplace, which allows an authenticated and an authorized user to install and exploit an old plugin version from the Marketplace which might have known vulnerabilities.
Solution:
The code uses deprecated or obsolete functions, which suggests that the code has not been actively reviewed or maintained.
The product does not perform an authorization check when an actor attempts to access a resource or perform an action.
