Crabbox prior to v0.12.0 contains a privilege escalation vulnerability that allows users with shared visibility-only access to obtain Code, WebVNC, and Egress agent tickets by sending POST requests to ticket endpoints. Attackers can exploit insufficient access control checks on the /v1/leases/:id/code/ticket, /v1/leases/:id/webvnc/ticket, and /v1/leases/:id/egress/ticket endpoints to obtain bridge-agent tickets and impersonate trusted lease-side bridges despite having only visibility permissions.
