CVE-2026-1734Public exploitNetwork attack vector

Unauthenticated business-state changes via optional middleware

Published Feb 1, 2026 · Updated Feb 1, 2026

Missing authorization in CRMEB 5.6.0 through 5.6.3 allows remote attackers to alter business state through crontab endpoints. The route group passes false to AuthTokenMiddleware, making authentication optional, while CrontabController methods directly invoke order and distribution operations. No account or user interaction is required; exposed endpoints can cancel eligible unpaid orders, confirm deliveries, or unlink agent relationships.
