Plane is an an open-source project management tool. In plane.io, a guest user doesn't have a permission to access https[:]//app[.]plane[.]so/[:]slug/settings. Prior to Plane version 1.2.0, a problem occurs when the /api/workspaces/:slug/members/ is accessible by guest and able to list of users on a specific workspace that they joined.
