{"id":"CVE-2026-53471","summary":"Migration-planner: agent api ignores jwt source_id claim","details":"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.","modified":"2026-07-08T08:10:13.442151635Z","published":"2026-06-10T13:55:41.253Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53471.json","cna_assigner":"redhat","cwe_ids":["CWE-639"]},"references":[{"type":"ADVISORY","url":"https://access.redhat.com/security/cve/CVE-2026-53471"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53471.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-53471"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2487070"},{"type":"FIX","url":"https://github.com/kubev2v/migration-planner/pull/1213"},{"type":"PACKAGE","url":"https://github.com/kubev2v/migration-planner"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/kubev2v/migration-planner","events":[{"introduced":"0"},{"fixed":"a11665c07c4813a6eb7ce7a52e272b5c586cae30"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"0.13.5"}],"source":["AFFECTED_FIELD","CPE_RANGE"],"cpe":"cpe:2.3:a:kebev2v:migration_assessment:*:*:*:*:*:*:*:*"}}],"versions":["v0.13.4","v0.13.3","v0.13.2","v0.13.1","v0.13.0","v0.12.0","v0.11.0","v0.10.0","v0.9.0","v0.8.0","v0.7.0","v0.6.0","v0.5.1","v0.5.0","v0.4.0","v0.3.0","v0.2.1","v0.2.0-1","v0.2.0","0.1.4-1","0.1.4","0.1.3","0.1.2","0.1.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-53471.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:N"}]}
