github.com/mattermost/mattermost-server is vulnerable to Improper Access Control. The vulnerability exists due to a lack of permission checks in the library, allowing an attacker to access the playbook and modify it. This can occur if the user was once a member of the team, gained permissions to the playbook, and was subsequently removed from the team.
