Description
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.

Technical Analysis
CVE-2026-109171 describes a missing authorization vulnerability in yshop-crm through version 2.1.3. The vulnerability exists because the CrmContractController lacks the @PreAuthorize annotation, and the approver checks are commented out. This allows any authenticated back-office user to call the POST /admin-api/crm/contract/check endpoint to approve or reject contracts without proper permission validation. As a result, attackers can manipulate contract statuses, affecting customer deal records and inventory management.
Potential Impact
An attacker with authenticated back-office access can approve contracts to alter customer deal and purchase data or reject contracts to return products to stock. This could lead to unauthorized changes in business transactions and inventory, potentially causing financial discrepancies or operational disruption.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict access to the affected API endpoint to only trusted users and monitor for unauthorized contract approval or rejection activities.
