Summary
CVE-2023-6547 is a vulnerability affecting Mattermost that allows users with permissions to a playbook but no current membership to the team associated with the playbook to access and modify it. This issue occurs due to Mattermost's failure to validate team membership during playbook access. If a user was a former member of the team and was granted playbook permissions before being removed, they can still manipulate the playbook. This security weakness could potentially result in unauthorized modifications to critical workflows.
