github.com/mattermost/mattermost-server is vulnerable to a Denial of Service (DoS). The vulnerability is due to improper validation of the length of the emoji value in the custom user status, allowing an attacker to send a very long string as an emoji value multiple times, causing high resource consumption and possibly crashing the server.
