Upgrade github.com/kubev2v/assisted-migration-agent to 0.16.0
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for github.com/kubev2v/assisted-migration-agent

How to Check if You Are Affected

To determine whether your application is affected by CVE-2026-53475, inspect your project dependencies for Assisted Migration Agent:

inspect dependencies for github.com/kubev2v/assisted-migration-agent

Analyze the terminal output to locate any version of Assisted Migration Agent in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.16.0), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-295: Improper Certificate Validation, where the product does not validate, or incorrectly validates, a certificate. In Assisted Migration Agent, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

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.
