Summary

Mattermost fails to strip `embeds` from `metadata` when broadcasting `posted` events

Details

Mattermost does not strip embeds from metadata when broadcasting posted events.

This allows users to include arbitrary embeds in posts, which are then broadcasted via websockets. This can be exploited in many ways, for example to create permalinks with fully customizable content or to trigger a client Side Denial of Service (DoS) by sending a permalink with a non-string message.

The advisory metadata references the appropriate go pseudo version available from pkg.go.dev

Severity ?

3.1 (Low) - CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:L

Summary

Mattermost versions 9.11.x <= 9.11.0 and 9.5.x <= 9.5.8 fail to validate that the message of the permalink post is a string, which allows an attacker to send a non-string value as the message of a permalink post and crash the frontend.
