Sylius before 1.12.25, 1.13.17, 1.14.20, 2.1.16, and 2.2.9 JWT Audience Confusion Allows Admin API Authentication

Published Sep 27, 2026 · Updated Oct 6, 2026 · Assigned by VulnCheck

Description

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.
