What is CVE-2025-64066?
CVE-2025-64066 is a high-severity missing authorization vulnerability in n/a, published on 25 Nov 2025. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
Primakon Pi Portal 1.0.18 REST /api/v2/user/register endpoint suffers from a Broken Access Control vulnerability. The endpoint fails to implement any authorization checks, allowing unauthenticated attackers to perform POST requests to register new user accounts in the application's local database. This bypasses the intended security architecture, which relies on an external Identity Provider for initial user registration and assumes that internal user creation is an administrative-only function. This vector can also be chained with other vulnerabilities for privilege escalation and complete compromise of application. This specific request can be used to also enumerate already registered user accounts, aiding in social engineering or further targeted attacks.
