  "details": "### Summary\nThe checkout component improperly filters URL-writable properties, allowing authenticated users to inject arbitrary key-value pairs into server provisioning parameters. Because bundled server extensions prioritize these user-supplied properties over administrator-defined configurations, a regular user can override hosting plans and resource limits at checkout without special privileges.\n\n### Technical Details\nThe `Checkout` Livewire component (`app/Livewire/Products/Checkout.php`) exposes the `$checkoutConfig` property to URL query parameters via the `#[Url]` attribute (aliased as `config`). \n\nWhen processing this input:\n1. Validation rules are dynamically generated *only* for keys explicitly defined by an extension\u0027s `getCheckoutConfig()` method. Any undefined keys injected into the query parameter bypass validation entirely.\n2. The cart component (`app/Livewire/Cart.php`) stores all keys from `checkout_config` directly into the database without sanitation:\n```php\n   foreach ($item-\u003echeckout_config as $key =\u003e $value) {\n       $service-\u003eproperties()-\u003eupdateOrCreate([\u0027key\u0027 =\u003e $key], [\u0027value\u0027 =\u003e $value]);\n   }\n```\n3. During server provisioning, app/Helpers/ExtensionHelper.php retrieves these stored properties and passes them to the extension\u0027s createServer() method.\n\nBecause of how individual server extensions handle these properties, user-injected data overrides intended administrator settings.\n\n### Impact\nThis is a business logic flaw that allows remote, authenticated users to manipulate server provisioning parameters.\n\nDepending on the active extension, this leads to unauthorized overrides of core resource limits (such as CPU, RAM, storage, or package tiers). No administrative privileges are required to exploit this vulnerability.",
