Until an official fix is available, restrict access to the affected endpoints to trusted users only and monitor for suspicious access patterns. Implement additional authorization checks on the affected endpoints to prevent unauthorized data access.
Description
CVE-2026-102365 is a high-severity vulnerability in gz-yami mall4j up to version 4.0 where authorization checks are missing on certain GET endpoints in the UserAddrController. Authenticated attackers can access endpoints that expose customer address data, including names, phone numbers, and postal information. This allows unauthorized data harvesting of sensitive customer information.
