## Overview

Crabbox prior to v0.12.0 contains an authentication bypass vulnerability that allows non-admin shared-token callers to impersonate other owners or organizations by spoofing identity headers. Attackers can inject malicious X-Crabbox-Owner and X-Crabbox-Org headers in requests authenticated with a shared token to bypass authorization checks and access owner/org-scoped lease operations belonging to victim accounts.
