Vulnerabilities

[This CNA information record relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.]<br /> XAPI can configure different users with different roles, using Role<br /> Based Access Control. For more details, see:<br /> <br /> https://docs.xenserver.com/en-us/xencenter/current-release/rbac-overview.html#rbac-roles<br /> <br /> The pool-admin role is fully privileged. Notably, users with this role<br /> can also SSH into the host as root.<br /> <br /> The other administrator roles are pool-operator, vm-power-admin and<br /> vm-admin, each of which are authorised to configure and manage various<br /> aspects of the system.<br /> <br /> Some settings are inadequately restricted, and can be set by a lower<br /> privilege of administrator than expected.<br /> <br /> * CVE-2026-23559: A vm-admin can set VBD.other_config:backend-local and<br /> turn arbitrary files in dom0 into VDIs (virtual disks) and give said<br /> disks to a VM they control. This is an arbitrary read and/or modify<br /> of files in dom0.<br /> <br /> * CVE-2026-23560: A vm-admin can set VM.other-config:is_system_domain<br /> and mark a VM as a system domain. System domains are ignored and<br /> left running during certain other host/pool operations, and may be<br /> hidden from view in tooling.<br /> <br /> * CVE-2026-23561: A vm-admin can set VM.other_config:storage_driver_domain<br /> and mark a VM as the storage domain for a particular host storage<br /> connection (PBD). Shutting down the VM can cause the PBD to be<br /> erroneously marked as unplugged when it is not.<br /> <br /> * CVE-2026-23562: Configuration of PCI passthrough is normally<br /> restricted to the pool-admin role. However one API was missing this<br /> check, allowing a vm-admin access to unintended host hardware.<br /> <br /> * CVE-2026-42486: A vm-admin can set the VM.platform:hvm_serial<br /> parameter, which should be restricted to the pool-admin role, as it<br /> can allow arbitrary dom0 file write.

A security flaw has been discovered in enquirer up to 2.4.1. Affected is the function Enquirer.set of the component Public Package API. The manipulation of the argument question.name results in improperly controlled modification of object prototype attributes. The attack can be launched remotely. The exploit has been released to the public and may be used for attacks. The project was informed of the problem early through an issue report.

A weakness has been identified in manjurulhoque django-job-portal up to dfa352f305bba44445ac5dc12e9b2a98c9dcd71f. Affected by this vulnerability is the function EditEmployeeProfileAPIView of the file accounts/api/views.py of the component Employee Dashboard Endpoint. This manipulation of the argument role causes improper access controls. The attack may be initiated remotely. The exploit has been made available to the public and could be used for attacks. This product uses a rolling release model to deliver continuous updates. As a result, specific version information for affected or updated releases is not available. The project was informed of the problem early through an issue report but has not responded yet.

When oxenstored is tearing a domain down, the node data is cleaned up<br /> but the usage counts are leaked.<br /> <br /> When the domain ID is eventually reused, the new domain can create fewer<br /> nodes before beeing deemed to be over quota.

A security vulnerability has been detected in aerostackdev aerostack-mcp up to 6315dfde7df0a15aaf743f88d91347115e09ba23. Affected by this issue is the function upload_media of the component mcp-whatsapp. Such manipulation of the argument media_url leads to server-side request forgery. The attack may be launched remotely. This product operates on a rolling release basis, ensuring continuous delivery. Consequently, there are no version details for either affected or updated releases. The project was informed of the problem early through an issue report but has not responded yet.

Cesanta Mongoose before 7.22 contains an out-of-bounds read in the built-in TLS server function mg_tls_server_recv_hello(), which uses an attacker-controlled session_id_len byte from a TLS ClientHello as a buffer index without validating it against the length of received data. A remote, unauthenticated attacker can send a single crafted ClientHello with an oversized session id length to read past the receive buffer, crashing any HTTPS, MQTTS, or WSS service built on MG_TLS_BUILTIN.

[This CNA information record relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.]<br /> <br /> <br /> The Windows PV drivers expose various facilities to userspace. Several<br /> of these have no security descriptor, and are therefore fully accessible<br /> to unprivileged users. These are:<br /> <br /> 1. XenCons, CVE-2025-27462<br /> 2. XenIface, CVE-2025-27463<br /> 3. XenBus, CVE-2025-27464
