Vulnerability from github – Published: 2026-08-05 09:31 – Updated: 2026-08-05 09:31

Details

Crater isolates data per company_id, and its Invoice/Estimate/Payment/Expense policies enforce both a Bouncer ability check and $user->hasCompany($model->company_id). CustomerPolicy's view/update/delete methods omit the company-ownership check entirely, checking only the blanket ability. Route-model-bound customer lookups and the bulk Customer::deleteCustomers() method are similarly unscoped (self::find($id) with no company filter). Any authenticated user of one company can read, reassign (steal), or delete another company's customer records, with deletion cascading to that customer's invoices and payments.

Severity

8.3 (High)
