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.
Critical [CVE-2026-47876] VMXNET3 out-of-bounds write vulnerability
VMware ESX contains an out-of-bounds write vulnerability in the VMXNET3 virtual network adapter. A malicious actor with local administrative privileges on a virtual machine with VMXNET3 virtual network adapter may exploit this issue to execute code on the host. Non VMXNET3 virtual adapters are not affected by this issue. Affected products named by the advisory: Cloud Foundation; vSphere Foundation; Telco Cloud Platform.
Critical [CVE-2026-59309] vCenter: VMware vCenter contains an authentication bypass vulnerability in the VMware Directory Service.
VMware vCenter contains an authentication bypass vulnerability in the VMware Directory Service. A malicious actor with network access to vCenter may exploit this issue to bypass authentication and gain unauthorized access to the system. Affected products named by the advisory: Cloud Foundation; vSphere Foundation; Telco Cloud Infrastructure; Telco Cloud Platform.
Critical [CVE-2026-59310] vCenter directory-traversal vulnerability
VMware vCenter contains a directory traversal vulnerability in the Syslog server. A malicious actor with network access to vCenter may exploit this issue to execute arbitrary code. Affected products named by the advisory: Cloud Foundation; vSphere Foundation; Telco Cloud Infrastructure; Telco Cloud Platform.
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.
Low [CVE-2026-41709] ESX insufficient logging vulnerability
VMware ESX contains an insufficient logging vulnerability. A malicious administrator could exploit this issue to perform certain operations without them being logged. 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.
Advisory [CVE-2021-21985] VMware vCenter Server and VMware Cloud Foundation: The vSphere Client (HTML5) contains a remote code execution vulnerability due to lack of input validation in the Virtual SAN Health Check plug-in which is enabled by default in vCenter Server
The vSphere Client (HTML5) contains a remote code execution vulnerability due to lack of input validation in the Virtual SAN Health Check plug-in which is enabled by default in vCenter Server. A malicious actor with network access to port 443 may exploit this issue to execute commands with unrestricted privileges on the underlying operating system that hosts vCenter Server. Affected product named by the advisory: VMware vCenter Server and VMware Cloud Foundation.
Advisory [CVE-2021-21972] VMware vCenter Server: The vSphere Client (HTML5) contains a remote code execution vulnerability in a vCenter Server plugin
The vSphere Client (HTML5) contains a remote code execution vulnerability in a vCenter Server plugin. A malicious actor with network access to port 443 may exploit this issue to execute commands with unrestricted privileges on the underlying operating system that hosts vCenter Server. This affects VMware vCenter Server (7.x before 7.0 U1c, 6.7 before 6.7 U3l and 6.5 before 6.5 U3n) and VMware Cloud Foundation (4.x before 4.2 and 3.x before 3.10.1.2).
Advisory [CVE-2020-3992] OpenSLP as used in VMware ESXi (7.0 before ESXi_7.0.1-0.0.16850804, 6.7 before ESXi670-202010401-SG, 6.5 before ESXi650-202010401-SG) has a use-after-free issue
OpenSLP as used in VMware ESXi (7.0 before ESXi_7.0.1-0.0.16850804, 6.7 before ESXi670-202010401-SG, 6.5 before ESXi650-202010401-SG) has a use-after-free issue. A malicious actor residing in the management network who has access to port 427 on an ESXi machine may be able to trigger a use-after-free in the OpenSLP service resulting in remote code execution.
