Summary

WIMOOR through commit ec86736 contains an authentication bypass in which the service trusts an unsigned X-USERINFO header. An unauthenticated remote attacker who reaches backend service ports directly, bypassing the gateway, can forge the companyid and manager or admin usertype values to impersonate any tenant and privilege level (CWE-290). This allows reading and modifying other tenants' orders, finance data, and Amazon seller authorizations.
