Technical description

Spikster through commit e1cdf8c contains a missing authentication vulnerability that allows unauthenticated remote attackers to access all API routes by exploiting the unattached CipiAuth middleware, which is registered but never applied to any route in the API routing configuration. Attackers can invoke approximately 50 unprotected API endpoints to enumerate and provision servers, reset root passwords, read and write arbitrary files on the host, and create database users.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
