Access Control Gap in Apache CloudStack 4.20.2.0 APIs
CVE-2025-59454 Published on November 27, 2025
Apache CloudStack: Lack of user permission validation leading to data leak for few APIs
In Apache CloudStack, a gap in access control checks affected the APIs - createNetworkACL
- listNetworkACLs
- listResourceDetails
- listVirtualMachinesUsageHistory
- listVolumesUsageHistory
While these APIs were accessible only to authorized users, insufficient permission validation meant that users could occasionally access information beyond their intended scope.
Users are recommended to upgrade to Apache CloudStack 4.20.2.0 or 4.22.0.0, which fixes the issue.
