What is CVE-2026-45723?

The Omni management platform for Kubernetes is vulnerable to a path traversal issue that allows an authenticated operator to manipulate the TalosVersion field without proper validation. This flaw could result in the exposure of sensitive information through error responses generated by the configured image-factory host. Attackers could leverage this vulnerability to probe internal endpoints, potentially disclosing diagnostics information while being restricted from redirecting to external hosts or executing write operations. This issue has been addressed in versions 1.6.6 and 1.7.3.

Affected Version(s)

omni < 1.6.6 < 1.6.6

omni >= 1.7.0, < 1.7.3 < 1.7.0, 1.7.3
