- Severity: CVSS 8.2 (High), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:L
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=total

- Published: 2026-08-05 · Updated: 2026-08-10

## Affected

- crater-invoice crater: 6.0.6

## Description

Crater's NotePolicy checks only a blanket Bouncer ability (manage-all-notes / view-all-notes) with no company-ownership comparison, unlike InvoicePolicy and other sibling policies which additionally verify ->hasCompany(->company_id). Any authenticated user of one company can read, edit, or delete another company's notes by ID.
