{"cve":"CVE-2026-53471","nvd":{"published":"2026-06-10T15:16:41.703","modified":"2026-06-17T14:45:23.597","status":"Analyzed","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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:N/I:H/A:N","score":7.7},"cwes":["CWE-639"],"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"],"products":["kebev2v:migration_assessment"],"source":"nvd","synced_at":"2026-10-19T22:38:48.522727527+00:00"},"epss":{"cve":"CVE-2026-53471","score":0.00287,"percentile":0.21227,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-2fqw-7c6r-2cq6","url":"https://osv.dev/vulnerability/GHSA-2fqw-7c6r-2cq6","summary":"Openshift Migration Advisor agent-API fails to validate JWT source_id claim, allowing cross-tenant data manipulation","modified":"2026-08-18T15:11:04.517237171Z","packages":[{"ecosystem":"Go","name":"github.com/kubev2v/migration-planner","purl":"pkg:golang/github.com/kubev2v/migration-planner","ranges":["<0.13.5"],"fixed":["0.13.5"]}]},{"id":"GO-2026-6228","url":"https://osv.dev/vulnerability/GO-2026-6228","summary":"Openshift Migration Advisor agent-API fails to validate JWT source_id claim, allowing cross-tenant data manipulation in github.com/kubev2v/migration-planner","modified":"2026-08-18T15:00:25.540744297Z","packages":[{"ecosystem":"Go","name":"github.com/kubev2v/migration-planner","purl":"pkg:golang/github.com/kubev2v/migration-planner","ranges":["<0.13.5"],"fixed":["0.13.5"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
