Users are affected if you do not specify algorithms in the `jwt.verify()` function. This issue has been fixed, please update to version 9.0.0 which removes the default support for the none algorithm in the `jwt.verify()` method. There will be no impact, if you update to version 9.0.0 and you don\u2019t need to allow for the `none` algorithm. If you need 'none' algorithm, you have to explicitly specify that in `jwt.verify()` options."}]}, "problemtype": {"problemtype_data": [{"description": [{"lang": "en", "value": "CWE-327"}]}]}, "data_version": "4.0", "CVE_data_meta": {"ID": "CVE-2022-23540", "ASSIGNER": "security-advisories@github.com"}}, "impact": {"baseMetricV3": {"cvssV3": {"scope": "UNCHANGED", "version": "3.1", "baseScore": 7.6, "attackVector": "NETWORK", "baseSeverity": "HIGH", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:H/A:L", "integrityImpact": "HIGH", "userInteraction": "NONE", "attackComplexity": "LOW", "availabilityImpact": "LOW", "privilegesRequired": "LOW", "confidentialityImpact": "LOW"}, "impactScore": 4.7, "exploitabilityScore": 2.8}}, "publishedDate": "2022-12-22T19:15Z", "configurations": {"nodes": [{"children": [], "operator": "OR", "cpe_match": [{"cpe23Uri": "cpe:2.3:a:auth0:jsonwebtoken:*:*:*:*:*:node.js:*:*", "cpe_name": [], "vulnerable": true, "versionEndIncluding": "8.5.1"}]}], "CVE_data_version": "4.0"}, "lastModifiedDate": "2023-02-27T19:56Z"}
