How to fix?

Upgrade github.com/mattermost/mattermost-server/v6 to version 7.8.13 or higher.

Overview

github.com/mattermost/mattermost-server/v6 is an open source, private cloud, Slack-alternative.

Affected versions of this package are vulnerable to Uncontrolled Resource Consumption ('Resource Exhaustion') due to the lack of control over the size of server logs. An attacker can potentially overflow the log by sending specially crafted requests to different endpoints. This is only exploitable if the server is configured to log all incoming requests.
