## Overview

The state that Kibana stores for an Observability Onboarding flow is not bound to the user who created the flow, and the routes that read and update that state do not verify ownership. An authenticated user who holds only generic read access to the space can therefore discover the onboarding flows of other users, read their onboarding state, and write arbitrary progress data into them. A tampered flow can also cause the owner's onboarding view to fail with a server error.

## Affected

- `kibana >= 8.9.0, < 8.19.19`
- `kibana >= 9.0.0, < 9.4.5`

## Remediation

Upgrade past the affected range:

- `kibana 9.4.5`
