CVE-2025-64066
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedPrimakon 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.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThe /api/v2/user/register endpoint in Primakon Pi Portal 1.0.18 lacks authorization checks, permitting unauthenticated users to create arbitrary accounts in the local database. This bypasses the intended security model that relies on an external Identity Provider for registration and assumes internal user creation is admin-only. The endpoint also leaks information about existing users.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Verify Primakon Project Contract Management versionLocate the installation directory or check software inventory/bill of materials for Primakon Project Contract Management version 1.0.18Affected if Version is exactly 1.0.18
-
Confirm API endpoint accessibilityAttempt a HEAD or OPTIONS request to https://[host]/api/v2/user/register (or the application's base path)Affected if Endpoint responds with HTTP 200 or 405 (method not allowed) indicating the endpoint exists and is reachable
-
Test unauthenticated user creationSend a POST request to /api/v2/user/register with a test payload containing username/email fields, without providing any authentication headers or tokensAffected if Request succeeds with HTTP 200/201 and returns a success message or user data without requiring authentication
-
Check for user enumerationSend POST requests to /api/v2/user/register with different email addresses (one known-existing and one random) without authentication, and compare the error messages or response codesAffected if Responses differ in a way that reveals whether a particular email/username already exists in the system (e.g., 'user already exists' vs 'account created')
A user is affected if Primakon Project Contract Management version 1.0.18 is running and the /api/v2/user/register endpoint accepts unauthenticated requests to create users or reveals existing user information.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement proper authorization checks on the /api/v2/user/register endpoint to restrict user creation to authenticated administrators only, and validate user existence without revealing account presence to unauthorized parties.
