Mattermost Server vulnerable to application crash from attacker-generated large response

Quick fix

GHSA-762v-rq7q-ff97 — github.com/mattermost/mattermost/server/v8: upgrade to the fixed version with the command below.

go get github.com/mattermost/mattermost/server/v8@v8.0.0-20240926115259-20ed58906adc

Details

Mattermost versions 9.10.x <= 9.10.2, 9.11.x <= 9.11.1 and 9.5.x <= 9.5.9 fail to prevent detailed error messages from being displayed in Playbooks which allows an attacker to generate a large response and cause an amplified GraphQL response which in turn could cause the application to crash by sending a specially crafted request to Playbooks.
