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."}],"source":{"advisory":"GHSA-qwph-4952-7xr6","discovery":"UNKNOWN"}},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2024-07-16T16:23:30.289495Z","id":"CVE-2022-23540","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2024-07-16T16:23:36.527Z"}},{"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2024-08-03T03:43:46.466Z"},"title":"CVE Program Container","references":[{"name":"https://github.com/auth0/node-jsonwebtoken/security/advisories/GHSA-qwph-4952-7xr6","tags":["x_refsource_CONFIRM","x_transferred"],"url":"https://github.com/auth0/node-jsonwebtoken/security/advisories/GHSA-qwph-4952-7xr6"},{"name":"https://github.com/auth0/node-jsonwebtoken/commit/e1fa9dcc12054a8681db4e6373da1b30cf7016e3","tags":["x_refsource_MISC","x_transferred"],"url":"https://github.com/auth0/node-jsonwebtoken/commit/e1fa9dcc12054a8681db4e6373da1b30cf7016e3"},{"url":"https://security.netapp.com/advisory/ntap-20240621-0007/","tags":["x_transferred"]}]}]},"dataVersion":"5.1"}
