GHSA-8vwh-pr89-4mw2 Laravel Pulse Allows Remote Code Execution via Unprotected Query Method

• Packagist laravel/pulse: < 1.3.1 → fixed in 1.3.1

A vulnerability has been discovered in Laravel Pulse that could allow remote code execution through the public `remember()` method in the `Laravel\Pulse\Livewire\Concerns\RemembersQueries` trait. This method is accessible via Livewire components and can be exploited to call arbitrary callables within the application. Impact An authenticated user with access to Laravel Pulse dashboard can execute arbitrary code by calling any function or static method that meets the following criteria: • The callable is a function or static method • The callable has no parameters or no strict parameter types Vulnerable Components • The `remember(callable $query, string $key = '')` method in `Laravel\Pulse\Livewire\Concerns\RemembersQueries` • Affects all Pulse card components that use this trait Attack Vectors The vulnerability can be exploited through Livewire component interactions, for example: ```php wire:click="remember('\\Illuminate\\Support\\Facades\\Config::all', 'config')" ``` Credit Thank you to Jeremy Angele for reporting this vulnerability.
