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." } ], "affected": [ { "versions": [ { "status": "affected", "version": "0", "lessThan": "0.13.5", "versionType": "semver" } ], "packageName": "migration-planner", "collectionURL": "https://github.com/kubev2v/migration-planner", "defaultStatus": "unaffected" } ], "references": [ { "url": "https://access.redhat.com/security/cve/CVE-2026-53471", "tags": [ "vdb-entry", "x_refsource_REDHAT" ] }, { "url": "https://bugzilla.redhat.com/show_bug.cgi?id=2487070", "name": "RHBZ#2487070", "tags": [ "issue-tracking", "x_refsource_REDHAT" ] }, { "url": "https://github.com/kubev2v/migration-planner/pull/1213" } ], "datePublic": "2026-06-07T00:00:00.000Z", "problemTypes": [ { "descriptions": [ { "cweId": "CWE-639", "description": "Authorization Bypass Through User-Controlled Key", "lang": "en", "type": "CWE" } ] } ], "x_redhatCweChain": "CWE-639: Authorization Bypass Through User-Controlled Key", "timeline": [ { "lang": "en", "time": "2026-06-09T17:48:04.857Z", "value": "Reported to Red Hat." }, { "lang": "en", "time": "2026-06-07T00:00:00.000Z", "value": "Made public." } ], "providerMetadata": { "orgId": "53f830b8-0a3f-465b-8143-3b8a9948e749", "shortName": "redhat", "dateUpdated": "2026-06-10T14:37:03.484Z" }, "x_generator": { "engine": "cvelib 1.8.0" } }, "adp": [ { "metrics": [ { "other": { "type": "ssvc", "content": { "timestamp": "2026-06-10T16:02:11.706466Z", "id": "CVE-2026-53471", "options": [ { "Exploitation": "none" }, { "Automatable": "no" }, { "Technical Impact": "total" } ], "role": "CISA Coordinator", "version": "2.0.3" } } } ], "title": "CISA ADP Vulnrichment", "providerMetadata": { "orgId": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "shortName": "CISA-ADP", "dateUpdated": "2026-06-10T16:02:20.123Z" } } ] } }
