VMware Avi Load Balancer Authorization Bypass Vulnerability

VMware Avi Load Balancer contains an authorization bypass vulnerability. A malicious actor on the network can access a limited subset of the Avi Control Plane without proper authorization. Affected versions: 32.1.1 (fixed in 32.1.2) 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-2026-47866 is an authorization bypass vulnerability affecting VMware Avi Load Balancer across multiple versions, allowing unauthenticated network-based attackers to access sensitive portions of the Avi Control Plane without proper credentials. With a CVSS score of 8.3, this vulnerability poses significant risk to organizations relying on Avi for load balancing and application delivery, as it undermines the security perimeter that protects critical infrastructure management interfaces. The vulnerability affects versions 22.1.1 through 32.1.1, requiring immediate patching across affected deployments to prevent unauthorized access to control plane functionality.

Casky.ai's 283 mapped security skills leverage Claude AI's extended reasoning to detect the attack patterns underlying this CWE-863 (Improper Authorization) vulnerability by correlating indicators across MITRE ATT&CK techniques TA0004 (Privilege Escalation) and TA0006 (Credential Access). Practitioners using Casky would identify suspicious findings such as unauthenticated API calls to Control Plane endpoints, unusual network segmentation bypass attempts, and lateral movement patterns from unprivileged network positions into restricted management zones. The platform's skill-based detection framework would surface behavioral anomalies including rapid enumeration of administrative interfaces, token-less authentication acceptance, and access to configuration management resources typically requiring multi-factor authentication—enabling security teams to detect exploitation attempts before control plane compromise occurs.
