CVE-2026-109171: yshop-crm missing authorization in contract approval

CVE-2026-109171 · Severity: medium · CVSS 4.3 · Published 2026-10-12

yshop-crm is a customer relationship management system used to manage contracts and customer purchases. A missing authorization check allows any authenticated back-office user to approve or reject contracts without proper permissions, potentially enabling unauthorized changes to customer orders, deal status, or inventory. An attacker with basic back-office access can manipulate contract data, approve fraudulent deals, or return products to stock without authorization.

Technical details

The CrmContractController endpoint POST /admin-api/crm/contract/check lacks @PreAuthorize annotation and has commented-out checks for approver identity and validity, allowing any authenticated user to bypass authorization. The vulnerability permits an authenticated attacker to invoke contract approval/rejection logic via the unauthenticated business layer, resulting in modification of customer deal status, purchase counts, and inventory without the required crm:contract:* permissions. No authentication bypass is required; exploitation requires valid back-office credentials.

Affected products

yshop-crm through 2.1.3
