Mattermost is vulnerable to Improper Access Control. The vulnerability is due to a failure to restrict the audience of the “custom_playbooks_playbook_run_updated” webhook event, allowing a guest on a channel with a linked playbook run to see all details of the playbook run when it is marked as finished.
