Certificate validation failures in SAML authentication in Apache CloudStack 4.20.3.0 and 4.22.1.0 on all platforms allow a malicious agent to forge a SAML response to the management server. The agent will have to spoof the ip address of the IdP or get an url of its own choosing registered in the management server, after which it can allow logging on with forged signatures. Users are recommended to upgrade to versions 4.20.3.1 or 4.22.1.1 and above, which fix this issue.

Aug 21, 2026Improper access control in CloudStack's annotation functionality allows unauthorized comment creation and disclosure.CVE-2026-66797 · Websites & servers · Apache Software Foundation · reported by security@apache.orgMedium 5.4
Improper access control in CloudStack's annotation functionality allows unauthorized comment creation and disclosure. The addAnnotation and listAnnotation APIs perform an ownership check when an entity's UUID is specified, but fail to honor its result correctly. This lets any authenticated user write annotations to, and disclose existing annotations/comments on, an entity they don't own by simply supplying its UUID. This issue affects Apache CloudStack: from 4.15.0.0 through 4.20.3.0 and from 4.21.0.0 through 4.22.1.0. Users are recommended to upgrade to version 4.20.3.1 or 4.22.1.1 or later, which fixes the issue.

Aug 21, 2026Improper authorization for CRUD operations on Project Roles and Project Role permissions for domain admins in CloudStack.CVE-2026-66722 · Websites & servers · Apache Software Foundation · reported by security@apache.orgHigh 7.2
Improper authorization for CRUD operations on Project Roles and Project Role permissions for domain admins in CloudStack. A Domain Admin can create, update, delete, and list project roles and project role permissions for projects in any domain, not just their own. The check only confirms the caller is a Domain Admin, without verifying whether the target project belongs to their domain or subdomain. This allows a malicious Domain Admin to tamper with project roles and permissions across unrelated domains. This issue affects Apache CloudStack: from 4.15.0.0 through 4.20.3.0 and from 4.21.0.0 through 4.22.1.0. Users are recommended to upgrade to version 4.20.3.1 or 4.22.1.1 or later, which fixes the issue.

Aug 21, 2026Authenticated pre-validation SSRF vulnerability in Apache CloudStack's template and ISO registration functionality.CVE-2026-61422 · Websites & servers · Apache Software Foundation · reported by security@apache.orgMedium 4.3
Authenticated pre-validation SSRF vulnerability in Apache CloudStack's template and ISO registration functionality. When registering a template or ISO, CloudStack makes a live HTTP HEAD/GET call to determine file size for secondary storage usage-limit checks, and this happens before URL validation is performed. However, this does not pose a malicious template or ISO registration risk, as URL validation still occurs prior to the actual download by the Secondary Storage VM.This issue affects Apache CloudStack: in 4.20.3.0 and from 4.21.0.0 through 4.22.1.0. Users are recommended to upgrade to version 4.20.3.1 or 4.22.1.1 or later, which fixes the issue.

Improper Neutralization of Special Elements used in a Command ('Command Injection') vulnerability in Apache CloudStack's run and get diagnostics functionality for the system VMs and virtual routers. An authenticated user holding the permissions required to invoke either `getDiagnosticsData` or `runDiagnostics` can achieve arbitrary command execution on the system VM and/or Virtual Router instances, with commands running as root (or as the diagnostics-process user, at minimum). This represents a full compromise of the affected instance and, depending on network segmentation, may provide a foothold for lateral movement within the CloudStack-managed infrastructure, including access to guest network traffic handled by the compromised Virtual Router. The getDiagnosticsData and runDiagnostics APIs are restricted to only Admin role accounts by default. This issue affects Apache CloudStack: from 4.20.0.0 through 4.20.3.0 and from 4.21.0.0 through 4.22.1.0. Users are recommended to upgrade to version 4.20.3.1 or 4.22.1.1 or later, which fixes the issue.

SSRF via Metalink Mirror URL Resolution: An authenticated tenant can register a template pointing to an attacker-controlled metalink file containing internal targets. The Secondary Storage VM will retrieve the data and persist it as a template file, which can later be downloaded through normal APIs. RCE on KVM hypervisor via NFS, Metalink files with/without Direct Downloads: An authenticated CloudStack tenant holding the default User role can execute arbitrary shell commands as root on the KVM hypervisor host that runs other tenants' VMs. This is cross-tenant root on the underlying compute, reachable via the public CloudStack API. When a User registers a VM template with directDownload=true and a URL pointing to a .metalink file, the management server fetches the metalink XML and dispatches download to the KVM agent. Inner URLs inside the metalink XML are never re-validated against the scheme allowlist. These issues affect Apache CloudStack: from 4.14.0.0 through 4.20.3.0 and from 4.21.0.0 through 4.22.1.0.

May 8, 2026Instances deployed via the Proxmox extension allow unauthorized access to instances belonging to other tenants.CVE-2026-25199 · Websites & servers · Apache Software Foundation · reported by security@apache.orgCritical 9.1
Instances deployed via the Proxmox extension allow unauthorized access to instances belonging to other tenants. This issue affects Apache CloudStack: from 4.21.0.0 through 4.22.0.0. The Proxmox extension for CloudStack improperly uses a user-editable instance setting, proxmox_vmid, to associate CloudStack instances with Proxmox virtual machines. Because this value is not restricted or validated against tenant ownership and Proxmox VM IDs are predictable, a non-privileged attacker can modify the setting to reference a VM belonging to another account. This allows unauthorized cross-tenant access and enables full control over the targeted VM, including starting, stopping, and destroying the virtual machine. Users are recommended to upgrade to version 4.22.0.1, which fixes this issue. As a workaround for the existing installations, editing of the proxmox_vmid instance detail by users can be prevented by adding this detail name to the global configuration parameter - user.vm.denied.details.

Jun 10, 2025In Apache CloudStack, a flaw in access control affects the listTemplates and listIsos APIs.CVE-2025-30675 · Websites & servers · Apache Software Foundation · reported by security@apache.orgMedium 4.7
In Apache CloudStack, a flaw in access control affects the listTemplates and listIsos APIs. A malicious Domain Admin or Resource Admin can exploit this issue by intentionally specifying the 'domainid' parameter along with the 'filter=self' or 'filter=selfexecutable' values. This allows the attacker to gain unauthorized visibility into templates and ISOs under the ROOT domain. A malicious admin can enumerate and extract metadata of templates and ISOs that belong to unrelated domains, violating isolation boundaries and potentially exposing sensitive or internal configuration details. This vulnerability has been fixed by ensuring the domain resolution strictly adheres to the caller's scope rather than defaulting to the ROOT domain. Affected users are recommended to upgrade to Apache CloudStack 4.19.3.0 or 4.20.1.0.

A privilege escalation vulnerability exists in Apache CloudStack versions 4.10.0.0 through 4.20.0.0 where a malicious Domain Admin user in the ROOT domain can get the API key and secret key of user-accounts of Admin role type in the same domain. This operation is not appropriately restricted and allows the attacker to assume control over higher-privileged user-accounts. A malicious Domain Admin attacker can impersonate an Admin user-account and gain access to sensitive APIs and resources that could result in the compromise of resource integrity and confidentiality, data loss, denial of service, and availability of infrastructure managed by CloudStack. Users are recommended to upgrade to Apache CloudStack 4.19.3.0 or 4.20.1.0, which fixes the issue with the following: * Strict validation on Role Type hierarchy: the caller's role must be equal to or higher than the target user's role. * API privilege comparison: the caller must possess all privileges of the user they are operating on. * Two new domain-level settings (restricted to the default admin): - role.types.allowed.for.operations.on.accounts.of.same.role.type: Defines which role types are allowed to act on users

When an Apache CloudStack user-account creates a CKS-based Kubernetes cluster in a project, the API key and the secret key of the 'kubeadmin' user of the caller account are used to create the secret config in the CKS-based Kubernetes cluster. A member of the project who can access the CKS-based Kubernetes cluster, can also access the API key and secret key of the 'kubeadmin' user of the CKS cluster's creator's account. An attacker who's a member of the project can exploit this to impersonate and perform privileged actions that can result in complete compromise of the confidentiality, integrity, and availability of resources owned by the creator's account.

Jan 13, 2025CloudStack users can add and read comments (annotations) on resources they are authorised to access.CVE-2025-22828 · Websites & servers · Apache Software Foundation · reported by security@apache.orgMedium 4.3
CloudStack users can add and read comments (annotations) on resources they are authorised to access. Due to an access validation issue that affects Apache CloudStack versions from 4.16.0, users who have access, prior access or knowledge of resource UUIDs can list and add comments (annotations) to such resources. An attacker with a user-account and access or prior knowledge of resource UUIDs may exploit this issue to read contents of the comments (annotations) or add malicious comments (annotations) to such resources. This may cause potential loss of confidentiality of CloudStack environments and resources if the comments (annotations) contain any privileged information. However, guessing or brute-forcing resource UUIDs are generally hard to impossible and access to listing or adding comments isn't same as access to CloudStack resources, making this issue of very low severity and general low impact. CloudStack admins may also disallow listAnnotations and addAnnotation API access to non-admin roles in their environment as an interim measure.

The CloudStack integration API service allows running its unauthenticated API server (usually on port 8096 when configured and enabled via integration.api.port global setting) for internal portal integrations and for testing purposes. By default, the integration API service port is disabled and is considered disabled when integration.api.port is set to 0 or negative. Due to an improper initialisation logic, the integration API service would listen on a random port when its port value is set to 0 (default value). An attacker that can access the CloudStack management network could scan and find the randomised integration API service port and exploit it to perform unauthorised administrative actions and perform remote code execution on CloudStack managed hosts and result in complete compromise of the confidentiality, integrity, and availability of CloudStack managed infrastructure. Users are recommended to restrict the network access on the CloudStack management server hosts to only essential ports.
