GHSA-vm9m-57jr-4pxh

Mattermost fails to limit the number of role names

Quick fix

GHSA-vm9m-57jr-4pxh — github.com/mattermost/mattermost/server/v8: upgrade to the fixed version with the command below.

go get github.com/mattermost/mattermost/server/v8@v9.4.2

Details

Mattermost versions 8.1.x before 8.1.9, 9.2.x before 9.2.5, 9.3.0, and 9.4.x before 9.4.2 fail to limit the number of role names requested from the API, allowing an authenticated attacker to cause the server to run out of memory and crash by issuing an unusually large HTTP request.
