OpenSLP as used in ESXi (7.0 before ESXi70U1c-17325551, 6.7 before ESXi670-202102401-SG, 6.5 before ESXi650-202102101-SG) has a heap-overflow vulnerability. A malicious actor residing within the same network segment as ESXi who has access to port 427 may be able to trigger the heap-overflow issue in OpenSLP service resulting in remote code execution.
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.
VMware NSX contains a weak password recovery mechanism vulnerability. An unauthenticated malicious actor may exploit this to enumerate valid usernames, potentially enabling brute-force attacks.
Impact: Username enumeration → credential brute force risk. Attack Vector: Remote, unauthenticated. Severity: Important. CVSSv3: 8.1 (High).
Acknowledgments: Reported by the National Security Agency.
Affected Products:VMware NSX 9.x.x.x, 4.2.x, 4.1.x, 4.0.x
NSX-T 3.x VMware Cloud Foundation (with NSX) 5.x, 4.5.x
Fixed Versions: NSX 9.0.1.0; 4.2.2.2/4.2.3.1 http://4.2.2.2/4.2.3.1 ; 4.1.2.7; NSX-T 3.2.4.3; CCF async patch (KB88287). Workarounds: None.
Broadcom VMware Aria Operations formerly known as vRealize Operations (vROps) contains a command injection vulnerability that allows an unauthenticated attacker to execute arbitrary commands, potentially leading to remote code execution during support‑assisted product migration.
VMware Cloud Foundation Operations contains multiple stored cross-site scripting vulnerabilities.A malicious actor with privileges to create policies, views or text-widgets may be able to inject scripts to perform administrative actions in VMware Cloud Foundation Operations.

A flaw was found in open-vm-tools.
VMware Workspace ONE Access, Identity Manager and vRealize Automation contain a privilege escalation vulnerability due to improper permissions in support scripts.
Description: VMware NSX contains a username enumeration vulnerability. An unauthenticated malicious actor may exploit this to enumerate valid usernames, potentially leading to unauthorized access attempts.
Impact: Username enumeration → facilitates unauthorized access.
Attack Vector: Remote, unauthenticated.
Severity: Important.
CVSSv3: 7.5 (High).

Server Side Request Forgery in vRealize Operations Manager API (CVE-2021-21975) prior to 8.4 may allow a malicious actor with network access to the vRealize Operations Manager API can perform a Server Side Request Forgery attack to steal administrative credentials.
VMware ESXi contains an authentication bypass vulnerability. A malicious actor with sufficient Active Directory (AD) permissions can gain full access to an ESXi host that was previously configured to use AD for user management https://blogs.vmware.com/vsphere/2012/09/joining-vsphere-hosts-to-active-directory.html by re-creating the configured AD group ('ESXi Admins' by default) after it was deleted from AD.
VMware Aria Operations contains a privilege escalation vulnerability. A malicious actor with privileges in vCenter to access Aria Operations may leverage this vulnerability to obtain administrative access in VMware Aria Operations. To remediate CVE-2026-22721, apply the patches listed in the 'Fixed Version' column of the 'Response Matrix' found in VMSA-2026-0001 https://support.broadcom.com/web/ecx/support-content-notification/-/external/content/SecurityAdvisories/0/36947 .
VMware ESXi, Workstation, and Fusion contain an information disclosure vulnerability due to an out-of-bounds read in HGFS. A malicious actor with administrative privileges to a virtual machine may be able to exploit this issue to leak memory from the vmx process.
