VMware Avi Load Balancer Authentication Bypass Vulnerability

VMware Avi Load Balancer contains an authentication bypass vulnerability. A malicious user with network access may be able to access the Avi Control plane by bypassing the authentication mechanism. Affected versions: 31.1.1 through 31.2.2 (fixed in 31.2.2-2p3) 30.1.1 through 30.2.6 (fixed in 30.2.7) 22.1.1 through 22.1.7 (fixed in 30.2.7)

Casky was already ahead

This CVE exploits attack patterns that Casky's 283matched skills already investigate — long before this vulnerability was disclosed. Claude's reasoning model maps these techniques to MITRE ATT&CK, so practitioners who ran these skills have already seen the threat behaviour in their findings.

Analysis

CVE-2026-47865 is a critical authentication bypass vulnerability (CVSS 9.8) affecting VMware Avi Load Balancer across multiple versions, allowing attackers with network access to circumvent authentication controls and directly access the Avi Control plane. This vulnerability is particularly dangerous because load balancers are typically trusted infrastructure components sitting at network boundaries, making them high-value targets for lateral movement and credential theft. Organizations running affected versions of Avi (31.1.1-31.2.2, 30.1.1-30.2.6, or 22.1.1-22.1.7) face immediate risk of unauthorized administrative access, configuration manipulation, and potential compromise of downstream applications and services.

Casky's security skills leverage Claude AI with extended reasoning to detect attack patterns associated with TA0004 (Privilege Escalation) and TA0006 (Credential Access) techniques by analyzing authentication mechanisms, session tokens, and access control implementations. Among the 283 matching skills, practitioners would identify findings related to improper authentication validation, missing or weak access controls, and anomalous authentication bypass attempts—such as unusual API requests lacking proper credentials reaching privileged endpoints, suspicious session establishment patterns, or unexpected Control plane access logs from unauthorized sources. These skill-driven detections would surface the specific authentication pathways being exploited, enabling teams to correlate network telemetry, access logs, and API activity to confirm exploitation attempts and immediately isolate affected systems while patching to versions 31.2.2-2p3 or 30.2.7+.
