CVE-2026-53471

Migration-planner: agent api ignores jwt source_id claim

State: Published
Severity: 9.6 Critical
Published: Jun 10, 2026
Updated: Jun 10, 2026
Reserved: Jun 9, 2026

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.
