Description

Mattermost versions 10.2.0, 9.11.x <= 9.11.5, 10.0.x <= 10.0.3, 10.1.x <= 10.1.3 fail to properly validate post types, which allows attackers to deny service to users with the sysconsole_read_plugins permission via creating a post with the custom_pl_notification type and specific props.

Affected configurations

• mattermost mattermost server (>= 9.11.0 < 9.11.6) • mattermost mattermost server (>= 10.0.0 < 10.0.4) • mattermost mattermost server (>= 10.1.0 < 10.1.4) • mattermost mattermost server (>= 10.2.0 < 10.2.1)
