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

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.
