# CVE-2026-22238

> 10.0 CRITICAL

## Beschreibung

The vulnerability exists in BLUVOYIX due to improper authentication in the BLUVOYIX admin APIs. An unauthenticated remote attacker could exploit this vulnerability by sending specially crafted HTTP requests to the vulnerable admin API to create a new user with admin privileges. Successful exploitation of this vulnerability could allow the attacker to gain full access to customers' data and completely compromise the targeted platform by logging in to the newly-created admin user.
