What is CVE-2026-92459?

The yshop-crm application through version 2.1.3 is susceptible to a missing authorization vulnerability that affects the 'receiveCustomer' endpoint within the CrmCluesController. This flaw enables authenticated back-office users to reassign sales leads without adequate permission checks, allowing unauthorized access and potential lead theft. Attackers can manipulate the endpoint to change the ownerUserId of leads, bypassing proper access controls, and there is no logging or limitation to prevent bulk reassignment of leads. This poses significant risks to data integrity and user trust.

Affected Version(s)

yshop-crm 0 <= 2.1.3
