AI Analysis
Technical Summary
CVE-2026-47865 is an authentication bypass vulnerability in VMware Avi Load Balancer. A remote attacker with network access can bypass the authentication mechanism to gain unauthorized access to the Avi Control plane. The vulnerability affects versions 22.1.1 through 22.1.7, 30.1.1 through 30.2.6, and 31.1.1 through 31.2.2. Fixes are available in versions 30.2.7 and 31.2.2-2p3.
