CVE-2026-53471 Details
Description
A flaw was found in migration-planner. The agent-API middleware processes JSON Web Tokens (JWTs) for authentication, but its UpdateSourceInventory and UpdateAgentStatus handlers fail to validate the source_id claim within these tokens against the requested source ID. This oversight allows an authenticated attacker with a valid agent token to manipulate data across different tenants, leading to a complete collapse of tenant isolation. This could result in unauthorized overwriting of victim inventory, planting of malicious credential URLs, or corruption of migration assessments.
A vulnerability exists in the KubeV2V Migration-Planner's agent-API middleware, which processes JSON Web Tokens (JWTs) for authentication. The issue arises because the UpdateSourceInventory and UpdateAgentStatus handlers do not validate the source_id claim in these tokens against the requested source ID. This flaw allows an authenticated attacker with a valid agent token to manipulate data across different tenants, effectively breaking tenant isolation. The exploitation of this vulnerability could lead to unauthorized overwriting of inventory, insertion of malicious credential URLs, or corruption of migration assessments.
The vulnerability has been addressed in a recent pull request, which can be found on the KubeV2V Migration-Planner GitHub repository.
