An authenticated user (including read-only-scoped tokens for the read path) can supply a path containing `../` sequences to read arbitrary files outside the library directory; a user with write access can write arbitrary files, enabling remote code execution via SSH authorized_keys or cron injection. This is a distinct, separately unpatched traversal from the previously fixed CVE-2021-21298 (Projects API)."}], "problemTypes": [{"descriptions": [{"lang": "en", "description": "CWE-22", "cweId": "CWE-22", "type": "CWE"}]}], "affected": [{"vendor": "node-red", "product": "node-red", "programFiles": ["packages/node_modules/@node-red/runtime/lib/storage/localfilesystem/library.js"], "versions": [{"version": "0", "lessThanOrEqual": "*", "status": "affected", "versionType": "custom"}], "defaultStatus": "unaffected"}], "metrics": [{"cvssV3_1": {"version": "3.1", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H", "baseScore": 7.2, "baseSeverity": "HIGH"}}], "references": [{"url": "https://github.com/node-red/node-red"}, {"url": "https://github.com/node-red/node-red/blob/master/packages/node_modules/@node-red/runtime/lib/storage/localfilesystem/library.js"}], "credits": [{"lang": "en", "value": "Alibek Baxtiyorov", "type": "finder"}], "providerMetadata": {"orgId": "309f9ea4-e3e9-4c6c-b79d-e8eb01244f2c", "shortName": "TuranSec", "dateUpdated": "2026-08-05T12:26:16.758Z"}}}}
