2DescriptionGitHub Advisory
nova-toggle-5 enables fliping booleans in the index. Prior to version 1.3.0, the toggle endpoint (POST/nova-vendor/nova-toggle/toggle/{resource}/{resourceId}) was protected only by web + auth:<guard> middleware. Any user authenticated on the configured guard could call the endpoint and flip boolean attributes on any Nova resource - including users who do not have access to Nova itself (for example, frontend customers sharing the web guard with the Nova admin area). The endpoint also accepted an arbitrary attribute parameter, which meant a valid caller could toggle any boolean column on the underlying model - not just columns exposed as Toggle fields on the resource. This issue has been patched in version 1.3.0.
