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’t need to allow for the `none` algorithm. If you need 'none' algorithm, you have to explicitly specify that in `jwt.verify()` options."},{"lang":"es","value":"En las versiones `&lt;=8.5.1` de la librería `jsonwebtoken`, la falta de definición del algoritmo en la función `jwt.verify()` puede provocar que se omita la validación de firmas debido a que se utiliza de manera predeterminada el algoritmo `none` para la verificación de firmas. Los usuarios se ven afectados si no especifica algoritmos en la función `jwt.verify()`. Este problema se ha solucionado; actualice a la versión 9.0.0, que elimina la compatibilidad predeterminada con el algoritmo none en el método `jwt.verify()`. No habrá ningún impacto si actualiza a la versión 9.0.0 y no necesita permitir el algoritmo \"none\". Si necesita el algoritmo 'none', debe especificarlo explícitamente en las opciones `jwt.verify()`."}],"affected":[{"source":"security-advisories@github.com","affectedData":[{"vendor":"auth0","product":"node-jsonwebtoken","versions":[{"version":"<= 8.5.1","status":"affected"}]}]}],"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:U/C:L/I:H/A:L","baseScore":6.4,"baseSeverity":"MEDIUM","attackVector":"NETWORK","attackComplexity":"HIGH","privilegesRequired":"LOW","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"LOW","integrityImpact":"HIGH","availabilityImpact":"LOW"},"exploitabilityScore":1.6,"impactScore":4.7},{"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:L/I:H/A:L","baseScore":7.6,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"LOW","integrityImpact":"HIGH","availabilityImpact":"LOW"},"exploitabilityScore":2.8,"impactScore":4.7}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2024-07-16T16:23:30.289495Z","id":"CVE-2022-23540","options":[{"exploitation":"none"},{"automatable":"no"},{"technicalImpact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Secondary","description":[{"lang":"en","value":"CWE-287"}]},{"source":"nvd@nist.gov","type":"Primary","description":[{"lang":"en","value":"CWE-347"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:auth0:jsonwebtoken:*:*:*:*:*:node.js:*:*","versionEndIncluding":"8.5.1","matchCriteriaId":"7E5DD3C1-F5DD-4BFD-BCA3-561BC167CB35"}]}]}],"references":[{"url":"https://github.com/auth0/node-jsonwebtoken/commit/e1fa9dcc12054a8681db4e6373da1b30cf7016e3","source":"security-advisories@github.com","tags":["Patch"]},{"url":"https://github.com/auth0/node-jsonwebtoken/security/advisories/GHSA-qwph-4952-7xr6","source":"security-advisories@github.com","tags":["Third Party Advisory"]},{"url":"https://security.netapp.com/advisory/ntap-20240621-0007/","source":"security-advisories@github.com"},{"url":"https://github.com/auth0/node-jsonwebtoken/commit/e1fa9dcc12054a8681db4e6373da1b30cf7016e3","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Patch"]},{"url":"https://github.com/auth0/node-jsonwebtoken/security/advisories/GHSA-qwph-4952-7xr6","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Third Party Advisory"]},{"url":"https://security.netapp.com/advisory/ntap-20240621-0007/","source":"af854a3a-2127-422b-91ae-364da2661108"}]}}]}
