EPSS

• CVE-2026-53475: 0.25% estimated exploitation activity in the next 30 days; percentile 16.90 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

A flaw was found in assisted-migration-agent. The application hardcodes insecure Transport Layer Security (TLS) connections when communicating with vCenter. This vulnerability allows a Man-in-the-Middle (MITM) attacker to intercept and harvest vCenter administrator credentials. This can lead to unauthorized access to vCenter.

# Patch Next advisory brief: CVE-2026-53475

Advisory: Assisted Migration Agent: Hardcoded insecure Transport Layer Security (TLS) connections during vCenter communication
IDs: CVE-2026-53475, GHSA-8g5p-jxp9-457c
Record: https://patchnext.com/advisories/cve-2026-53475 (revision 2, source checked 26 Oct 2026, 15:28 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Critical (CVSS 9.3)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: github.com/kubev2v/assisted-migration-agent 0.16.0. A vendor fix does not mean a deployment is fixed.

## Affected components
- Go github.com/kubev2v/assisted-migration-agent: affected < 0.16.0; fixed in 0.16.0

## Suggested inspection (read-only)
- Go github.com/kubev2v/assisted-migration-agent: check the installed version with your package manager.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on github.com/kubev2v/assisted-migration-agent.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.
