CVE-2026-92461
yshop-crm through 2.1.3 contains a missing authorization vulnerability in the GET /admin-api/crm/flow/flow-users endpoint that allows any logged-in back-office user to access approval workflow data. Attackers can retrieve approval chain topology, step ordering, approver identifiers, and personal information including login names, nicknames, departments, email addresses, mobile numbers and last login IP addresses.
What this means for your business
- An attacker can use it remotely, over a network, with an ordinary user login, and without anyone at your company clicking anything.
What to do
- 1Ask your IT team or provider whether any of your systems use the affected product.
- 2If you do, follow the vendor's guidance. No patch reference has been published yet.
