CVE-2026-92455

yshop-crm through 2.1.3 contains an insecure direct object reference vulnerability that allows authenticated sales users to access other users' customer records by supplying arbitrary ids. Attackers can enumerate ids against the get, update, delete and do-open endpoints to read contact details, overwrite or delete customers, or release them into the public pool.

yshop-crm through 2.1.3 contains a missing authorization vulnerability that allows any authenticated back-office user to approve or reject invoices via POST /admin-api/crm/invoice/check. The CrmInvoiceController check handler lacks @PreAuthorize and approver checks are commented out, letting attackers bypass the invoice approval workflow by supplying any invoice id.

yshop-crm through 2.1.3 contains a missing authorization vulnerability that allows any authenticated back-office user to approve or reject receivables records by calling POST /admin-api/crm/contract-receivables/check. The handler lacks a @PreAuthorize check and the approver checks in CrmContractReceivablesServiceImpl.check are commented out, so attackers can approve records by id, inflating contract return_money and forging approval logs.

yshop-crm through 2.1.3 contains a missing authorization vulnerability that allows any authenticated back-office user to approve or reject contracts by calling POST /admin-api/crm/contract/check. Because CrmContractController lacks @PreAuthorize and approver checks are commented out, attackers can approve contracts to alter customer deal and purchase data or reject them to return products to stock.

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.

yshop-crm through 2.1.3 fails to enforce authorization checks on the CrmFlowController deleteFlowStep endpoint, allowing any authenticated back-office user to delete arbitrary approval workflow steps. Attackers can invoke the DELETE /admin-api/crm/flow/delete-step endpoint without required permissions to remove approval steps that control contract, receivable, and invoice finalization processes.

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.

yshop-crm through 2.1.3 fails to enforce authorization on the GET /admin-api/crm/operatelog/page endpoint, allowing any authenticated back-office user to access the installation-wide audit trail. Attackers can query the operation log to retrieve operator names, display nicknames, client IP addresses, User-Agent strings, request URLs, action details, and customer identifiers without proper permission checks.

yshop-crm through 2.1.3 contains a missing authorization vulnerability in the CrmCluesController receiveCustomer endpoint that allows authenticated back-office users to claim sales leads without proper permission checks. Attackers can invoke the lead-claim endpoint to reassign leads from other employees to themselves by overwriting the ownerUserId field, with no access logging or quota validation to prevent bulk lead theft.

yshop-crm through 2.1.3 contains a missing authorization vulnerability in the StoreProductController onSale handler that allows authenticated back-office users to modify product sale status. Attackers can invoke the GET /admin-api/product/store-product/sale endpoint with sequential product IDs to withdraw entire product catalogs from sale or re-enable withdrawn products without proper permission checks.
