Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

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)

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · low confidence
Developing — this CVE was published recently and its authoritative NVD entry is still being established, so we're holding a technical summary until the source data settles rather than publish something unreliable. Re-checking after 2026-08-01.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

Recommended fix High confidence

32.1.2, 31.2.2-2p3, or 30.2.7 depending on your current branch

  1. Identify the currently running VMware Avi Load Balancer version using the Avi UI or CLI (show version command)
  2. If running version 32.1.1, upgrade to version 32.1.2
  3. If running version 31.1.1 through 31.2.2, upgrade to version 31.2.2-2p3
  4. If running version 30.1.1 through 30.2.6, upgrade to version 30.2.7
  5. If running version 22.1.1 through 22.1.7, upgrade to version 30.2.7
  6. After upgrade, verify the Avi Control Plane is accessible only with proper authentication
  7. Review access control list configurations to ensure no unauthorized access is possible
Caveat Upgrading across major version branches (e.g., from 22.x to 30.x) may require compatibility review and could impact existing configurations or integrations
