solidtime is an open-source time-tracking app. Prior to version 0.11.6, the project detail endpoint GET /api/v1/organizations/{org}/projects/{project} allows any authenticated Employee to access any project in the organization by UUID, including private projects they are not a member of. The index() endpoint correctly applies the visibleByEmployee() scope, but show() does not. This issue has been patched in version 0.11.6.
