Froxlor is open source server administration software. Prior to version 2.3.6, in `Domains.add()`, the `adminid` parameter is accepted from user input and used without validation when the calling reseller does not have the `customers_see_all` permission. This allows a reseller to attribute newly created domains to any other admin, bypassing their own domain quota (since the wrong admin's `domains_used` counter is incremented) and potentially exhausting another admin's quota. Version 2.3.6 fixes the issue.

GHSA-jvx4-xv3m-hrj4 — Froxlor has a Reseller Domain Quota Bypass via Unvalidated adminid Parameter in Domains.add()

Affected: Packagist: froxlor/froxlor

## Summary

In `Domains.add()`, the `adminid` parameter is accepted from user input and used without validation when the calling reseller does not have the `customers_see_all` permission. This allows a reseller to attribute newly created domains to any other admin, bypassing their own domain quota (since the wrong admin's `domains_used` counter is incremented) and potentially exhausting another admin's quota.

## Details

In `lib/Froxlor/Api/Commands/Domains.php`, the `add()` method accepts `adminid` as an optional parameter at line 327:

```php $adminid = intval($this->getParam('adminid', true, $this->getUserDetail('adminid'))); ```

The validation for this parameter only runs when the caller has `customers_see_all == '1'` (lines 410-421):

```php if ($this->getUserDetail('customers_see_all') == '1' && $adminid != $this->getUserDetail('adminid')) { $admin_stmt = Database::prepare(" SELECT * FROM `" . TABLE_PANEL_ADMINS . "` WHERE `adminid` = :adminid AND (`domains_used` < `domains` OR `domains` = '-1')"); $admin = Database::pexecute_first($admin_stmt, [ 'adminid' => $adminid ], true, true); if (empty($admin)) { Response::dynamicError("Selected admin cannot have any more domains or could not be found"); } unset($admin); } ```

When a reseller does **not** have `customers_see_all` (the common case for limited resellers), there is no `else` branch to force `$adminid = $this->getUserDetail('adminid')`. The unvalidated `$ad…
