{"id":"CVE-2022-23540","state":"PUBLISHED","title":"jsonwebtoken vulnerable to signature validation bypass due to insecure default algorithm in jwt.verify()","description":"In versions `<=8.5.1` of `jsonwebtoken` library, lack of algorithm definition in the `jwt.verify()` function can lead to signature validation bypass due to defaulting to the `none` algorithm for signature verification. 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.","publishedAt":"2022-12-22T18:02:24.770Z","updatedAt":"2025-02-13T16:32:21.578Z","severity":{"score":6.4,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:H/A:L","source":"GitHub_M"},"assigner":"GitHub_M","products":["auth0 node-jsonwebtoken"],"affected":[{"vendor":"auth0","product":"node-jsonwebtoken","versions":[{"version":"<= 8.5.1","status":"affected"}]}],"references":["https://github.com/auth0/node-jsonwebtoken/security/advisories/GHSA-qwph-4952-7xr6","https://github.com/auth0/node-jsonwebtoken/commit/e1fa9dcc12054a8681db4e6373da1b30cf7016e3","https://security.netapp.com/advisory/ntap-20240621-0007/"],"weaknesses":["CWE-287"],"ingestedAt":"2026-10-29T19:49:40.939Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2022/23xxx/CVE-2022-23540.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2022-23540","state":"PUBLISHED","datePublished":"2022-12-22T18:02:24.770Z","dateUpdated":"2025-02-13T16:32:21.578Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2022-01-19T21:23:53.795Z"},"containers":{"cna":{"title":"jsonwebtoken vulnerable to signature validation bypass due to insecure default algorithm in jwt.verify()","descriptions":[{"lang":"en","value":"In versions `<=8.5.1` of `jsonwebtoken` library, lack of algorithm definition in the `jwt.verify()` function can lead to signature validation bypass due to defaulting to the `none` algorithm for signature verification.
