Official description

OliveTin gives access to predefined shell commands from a web interface. In 3000.10.2 and earlier, OliveTin’s live EventStream broadcasts execution events and action output to authenticated dashboard subscribers without enforcing per-action authorization. A low-privileged authenticated user can receive output from actions they are not allowed to view, resulting in broken access control and sensitive information disclosure.
