## Overview

Sylius versions before 1.12.25, 1.13.17, 1.14.20, 2.1.16, and 2.2.9 fail to include firewall identification in JWT tokens issued by separate Admin and Shop API endpoints. Attackers can register a shop customer account using an administrator's email address and obtain a token that the Admin API resolves to that administrator, granting full administrative access.

## Remediation

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