AI Analysis
Technical Summary
VMware Avi Load Balancer contains an authorization bypass vulnerability (CVE-2026-47866) that enables an attacker with network access to bypass authorization controls and access a limited subset of the Avi Control Plane. The affected versions include 22.1.1 through 22.1.7, 30.1.1 through 30.2.6, 31.1.1 through 31.2.2, and 32.1.1. Fixes have been released in versions 30.2.7, 31.2.2-2p3, and 32.1.2 respectively.
Potential Impact
Successful exploitation could lead to unauthorized access to sensitive control plane functions, resulting in high confidentiality and integrity impact, and low availability impact as per the CVSS 3.1 score of 8.3. This could allow attackers to view or manipulate configuration or operational data within the Avi Load Balancer control plane.
Mitigation Recommendations
Fixes are available and have been released in VMware Avi Load Balancer versions 22.1.8 or later (implied by fix in 30.2.7), 30.2.7 or later, 31.2.2-2p3 or later, and 32.1.2 or later. Users should upgrade affected installations to these fixed versions to remediate the vulnerability. Patch status is confirmed by the version fixes stated. No vendor advisory content contradicts this guidance.
