VMware Security Advisories (VMSA) via NVD
Broadcom's VMSA portal is a JavaScript app with no stable public feed, so VulniPulse ingests VMware CVEs from NVD filtered to VMware's own CNAs (security@vmware.com and Broadcom's successor CNA) — official, CNA-published data covering ESXi, vCenter Server, NSX, Aria/vRealize, Cloud Foundation, Workstation/Fusion and VMware Tools. Each entry links back to the Broadcom/VMware advisory when NVD carries the reference.

High [CVE-2026-41012] BOSH: Traffic interception vulnerability in BOSH Director vCenter CPI allows attackers positioned between BOSH Director and…
Traffic interception vulnerability in BOSH Director vCenter CPI allows attackers positioned between BOSH Director and vCenter to impersonate vCenter REST API and capture administrator credentials via HTTP Basic auth, leading to complete virtualization infrastructure takeover. An attacker who can intercept traffic between the BOSH Director and vCenter can establish a malicious server impersonating the vCenter REST API. When the BOSH Director makes CPI calls to perform routine cloud infrastructure operations, the attacker captures the vCenter administrator username and password transmitted via HTTP Basic authentication. The vulnerability stems from insufficient authentication security in the communication protocol between BOSH Director and vCenter. While HTTPS may be used, the lack of proper certificate validation and pinning allows attackers to successfully impersonate vCenter endpoints. Because vCenter credentials typically grant full administrative control over the entire virtualization estate, successful credential capture yields complete takeover of every VM, datastore, and network the CPI manages. This exposure exists on every CPI call (including routine deployment operations, not just when tags are configured) and cannot be mitigated by supplying a CA certificate alone. Affected product named by the advisory: bosh-vsphere-cpi-release.
High [CVE-2026-41703] Out-of-bounds read vulnerability
VMware ESX, Workstation, and Fusion contain an out-of-bounds read vulnerability. A malicious actor with VM deployment privileges could trigger an out-of-bounds read, potentially leading to information disclosure or more likely a Denial-of-Service (DoS) condition of the host process. On Workstation and Fusion, the impact of this vulnerability is restricted to information disclosure. Affected products named by the advisory: Cloud Foundation; vSphere Foundation; Telco Cloud Platform.
High [CVE-2025-22225] VMware ESXi contains an arbitrary write vulnerability
VMware ESXi contains an arbitrary write vulnerability. A malicious actor with privileges within the VMX process may trigger an arbitrary kernel write leading to an escape of the sandbox. Affected products named by the advisory: VMware Cloud Foundation; VMware Telco Cloud Platform; VMware Telco Cloud Infrastructure.
High [CVE-2023-20900] VMware Tools: malicious actor that has been granted Guest Operation Privileges https://docs.vmware.com/en/VMware-vSphere/8.0/vsphere-security/GUID-6A952214-0E5E-4CCF-9D2A-90948FF643EC.html in a target virtual machine may be able to elevate their privileges if that target virtual machine has been assigned a more privileged Guest Alias https://vdc-download.vmware.com/vmwb-repository/dcr-public/d1902b0e-d479-46bf-8ac9-cee0e31e8ec0/07ce8dbd-db48-4261-9b8f-c6d3ad8ba472/vim.vm.guest.AliasManager.html
A malicious actor that has been granted Guest Operation Privileges in a target virtual machine may be able to elevate their privileges if that target virtual machine has been assigned a more privileged Guest Alias. AliasManager.html. Affected product named by the advisory: VMware Tools (open-vm-tools).
