CVE-2026-111694 Details
Description
qKnow through 2.4.3 contains a missing authentication vulnerability that allows unauthenticated remote attackers to access /flyflow workflow integration endpoints permitted in SecurityConfig. Attackers can POST sequential userId values to /flyflow/userById or call roleAll and deptListByParentDeptId to enumerate user phone numbers, roles, and department structure.
A missing authentication vulnerability exists in qKnow versions through 2.4.3, allowing unauthenticated remote attackers to access workflow integration endpoints under '/flyflow' that are permitted in the application's security configuration. Exploitation of this vulnerability enables attackers to post sequential user ID values to the '/flyflow/userById' endpoint or to call '/flyflow/roleAll' and '/flyflow/deptListByParentDeptId' to enumerate user phone numbers, roles, and department structures.
Remove the '/flyflow/**' pattern from the permitAll list in the security configuration and add appropriate authorization checks to the FlyFlowController methods.
