Account takeover via public customer update
Published Aug 20, 2026 · Updated Aug 20, 2026
Missing authorization in EverShop before 2.2.1 allows remote attackers to take over customer accounts via PATCH /api/customers/:id. The route is marked public in route.json, and updateCustomer.js loads a customer by the UUID in the URL path and writes attacker-supplied fields, including a newly hashed password, without checking authentication or record ownership. Any internet attacker who learns a customer UUID, which EverShop exposes in order-confirmation links and administrative URLs, can change that account's email and password, read back the updated record, and lock out the legitimate owner.
