Node-RED 1.2.7 and earlier has a vulnerability which allows arbitrary path traversal via the Projects API. If the Projects feature is enabled, a user with `projects.read` permission is able to access any file via the Projects API. The issue has been patched in Node-RED 1.2.8. The vulnerability applies only to the Projects feature which is not enabled by default in Node-RED. The primary workaround is not give untrusted users read access to the Node-RED editor."},{"lang":"es","value":"Node-Red es una programación de low-code para aplicaciones basadas en eventos diseñadas usando nodejs. Node-RED versiones 1.2.7 y anteriores, presentan una vulnerabilidad que permite un salto de ruta arbitrario por medio de la API Projects. Si la funcionalidad Proyects está habilitada, un usuario con el permiso \"projects.read\" puede acceder a cualquier archivo por medio de la API Proyects. El problema ha sido parcheado en Node-RED versión 1.2.8. La vulnerabilidad se aplica solo a la funcionalidad Proyects que no está habilitada por defecto en Node-RED. La solución alternativa principal es no dar acceso de lectura al editor de Node-RED para usuarios que no son confiables"}],"metrics":{"cvssMetricV31":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:L/I:N/A:N","baseScore":3.5,"baseSeverity":"LOW","attackVector":"NETWORK","attackComplexity":"HIGH","privilegesRequired":"LOW","userInteraction":"NONE","scope":"CHANGED","confidentialityImpact":"LOW","integrityImpact":"NONE","availabilityImpact":"NONE"},"exploitabilityScore":1.8,"impactScore":1.4},{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","baseScore":6.5,"baseSeverity":"MEDIUM","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"NONE","availabilityImpact":"NONE"},"exploitabilityScore":2.8,"impactScore":3.6}],"cvssMetricV2":[{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"2.0","vectorString":"AV:N/AC:M/Au:S/C:P/I:N/A:N","baseScore":3.5,"accessVector":"NETWORK","accessComplexity":"MEDIUM","authentication":"SINGLE","confidentialityImpact":"PARTIAL","integrityImpact":"NONE","availabilityImpact":"NONE"},"baseSeverity":"LOW","exploitabilityScore":6.8,"impactScore":2.9,"acInsufInfo":false,"obtainAllPrivilege":false,"obtainUserPrivilege":false,"obtainOtherPrivilege":false,"userInteractionRequired":false}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Secondary","description":[{"lang":"en","value":"CWE-22"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:nodered:node-red:*:*:*:*:*:node.js:*:*","versionEndExcluding":"1.2.8","matchCriteriaId":"FD380E45-4954-4427-90D5-66896B983B30"}]}]}],"references":[{"url":"https://github.com/node-red/node-red/commit/74db3e17d075f23d9c95d7871586cf461524c456","source":"security-advisories@github.com","tags":["Patch","Third Party Advisory"]},{"url":"https://github.com/node-red/node-red/releases/tag/1.2.8","source":"security-advisories@github.com","tags":["Release Notes","Third Party Advisory"]},{"url":"https://github.com/node-red/node-red/security/advisories/GHSA-m33v-338h-4v9f","source":"security-advisories@github.com","tags":["Third Party Advisory"]},{"url":"https://www.npmjs.com/package/%40node-red/runtime","source":"security-advisories@github.com"},{"url":"https://github.com/node-red/node-red/commit/74db3e17d075f23d9c95d7871586cf461524c456","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Patch","Third Party Advisory"]},{"url":"https://github.com/node-red/node-red/releases/tag/1.2.8","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Release Notes","Third Party Advisory"]},{"url":"https://github.com/node-red/node-red/security/advisories/GHSA-m33v-338h-4v9f","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Third Party Advisory"]},{"url":"https://www.npmjs.com/package/%40node-red/runtime","source":"af854a3a-2127-422b-91ae-364da2661108"}]}}]}
