{"id":"CVE-2026-53471","state":"PUBLISHED","title":"Migration-planner: agent api ignores jwt source_id claim","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.","publishedAt":"2026-06-10T13:55:41.253Z","updatedAt":"2026-06-10T16:02:20.123Z","severity":{"score":9.6,"label":"Critical","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:N","source":"redhat"},"assigner":"redhat","products":["migration-planner"],"affected":[{"packageName":"migration-planner","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThan":"0.13.5","versionType":"semver"}],"collectionURL":"https://github.com/kubev2v/migration-planner"}],"references":["https://access.redhat.com/security/cve/CVE-2026-53471","https://bugzilla.redhat.com/show_bug.cgi?id=2487070","https://github.com/kubev2v/migration-planner/pull/1213"],"weaknesses":["CWE-639"],"ingestedAt":"2026-10-29T20:12:16.098Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/53xxx/CVE-2026-53471.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-53471","state":"PUBLISHED","datePublished":"2026-06-10T13:55:41.253Z","dateUpdated":"2026-06-10T16:02:20.123Z","assignerShortName":"redhat","assignerOrgId":"53f830b8-0a3f-465b-8143-3b8a9948e749","dateReserved":"2026-06-09T17:03:29.627Z"},"containers":{"cna":{"title":"Migration-planner: agent api ignores jwt source_id claim","descriptions":[{"lang":"en","value":"A flaw was found in migration-planner.
