Administrator escalation via unchecked owner field

Published Jul 13, 2026 · Updated Jul 13, 2026

Privilege escalation in go-shiori Shiori before 1.8.0 allows remote authenticated users to gain administrator access via an account update. HandleUpdateLoggedAccount maps the PATCH /api/v1/auth/account owner value into an account update without checking that the caller is already an owner. Any registered non-owner can set owner to true and re-authenticate for an administrator JWT that permits all administrator-only operations.
