    User Impersonation

    @acastellon/auth is an Authorization Filtering for NodeJS Express Application (NTLM + LDAP + JWT + AWS Cognito + Azure AD/Entra ID + OIDC providers + SAML + env var secrets)

    Affected versions of this package are vulnerable to User Impersonation via the validateToken process. An attacker can gain unauthorized access to protected routes and potentially escalate privileges by sending crafted HTTP requests with spoofed auth-user and Host headers, causing the middleware to bypass token validation before standard authentication checks are performed. This is only exploitable if downstream services trust the auth-user or is-* headers provided by the client.

    How to fix User Impersonation?

    Upgrade @acastellon/auth to version 2.3.0 or higher.
