CVE-2026-53472Network attack vector

Stored XSS via unchecked credential URL scheme

Published Aug 14, 2026 · Updated Aug 14, 2026

Stored XSS in KubeV2V Migration Planner before 0.13.6 allows remote authenticated users to execute script in a victim's session. The migration-planner API stores a javascript: URL supplied in AgentStatusUpdate.CredentialUrl because its validator fails to reject that scheme, and the Hybrid Cloud Console renders the value as a link. Exploitation requires authenticated agent-status submission and a victim click; execution can expose data available to the victim's console session.
