The Real3D Flipbook WordPress plugin before 5.4 does not perform capability checks on several of its authenticated flipbook management actions, allowing users with Author-level access and above to delete other users' flipbook content and overwrite administrator-only global settings, which can be leveraged to store JavaScript that executes in the context of any visitor or administrator viewing the site.
