CVE-2026-55739
Crater - Missing Tenant-Ownership Check in CustomerPolicy Allows Cross-Company Customer Data Theft and Deletion
CVSS Score
8.2
EPSS Score
0.0%
EPSS Percentile
0th
Crater isolates data per company_id, and its Invoice/Estimate/Payment/Expense policies enforce both a Bouncer ability check and ->hasCompany(->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 with no company filter).
