## Overview

Rejetto HFS 3.0.0 through 3.2.0 accepts state-changing API requests via the GET method and exempts GET requests from its anti-CSRF header check. A remote attacker can perform administrative actions including account creation and configuration changes leading to code execution - by causing a logged-in administrator's browser to navigate to a crafted URL, or without any credentials against default installations when the attack originates from the server's own machine.

## Affected

- `hfs >= 3.0.0 < 3.2.1`

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
