CVE-2026-92463
yshop-crm through 2.1.3 contains an authorization failure in the GET /admin-api/system/user/page endpoint where the @PreAuthorize annotation is commented out, allowing authenticated back-office users without system:user:list permission to enumerate all users. Attackers with valid back-office credentials and a role with data scope ALL can retrieve the complete user directory including login names, nicknames, departments, email addresses, mobile numbers, and last login information.
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.
