{"id":"GHSA-hjrf-2m68-5959","summary":"jsonwebtoken's insecure implementation of key retrieval function could lead to Forgeable Public/Private Tokens from RSA to HMAC","details":"# Overview\n\nVersions `\u003c=8.5.1` of `jsonwebtoken` library can be misconfigured so that passing a poorly implemented key retrieval function (referring to the `secretOrPublicKey` argument from the [readme link](https://github.com/auth0/node-jsonwebtoken#jwtverifytoken-secretorpublickey-options-callback)) will result in incorrect verification of tokens. There is a possibility of using a different algorithm and key combination in verification  than the one that was used to sign the tokens. Specifically, tokens signed with an asymmetric public key could be verified with a symmetric HS256 algorithm. This can lead to successful validation of forged tokens. \n\n# Am I affected?\n\nYou will be affected if your application is supporting usage of both symmetric key and asymmetric key in jwt.verify() implementation with the same key retrieval function. \n\n# How do I fix it?\n \nUpdate to version 9.0.0.\n\n# Will the fix impact my users?\n\nThere is no impact for end users","aliases":["CVE-2022-23541"],"modified":"2026-03-11T07:49:31.366060Z","published":"2022-12-22T03:33:19Z","database_specific":{"github_reviewed_at":"2022-12-22T03:33:19Z","nvd_published_at":"2022-12-22T18:15:00Z","cwe_ids":["CWE-1259","CWE-287"],"severity":"MODERATE","github_reviewed":true},"references":[{"type":"WEB","url":"https://github.com/auth0/node-jsonwebtoken/security/advisories/GHSA-hjrf-2m68-5959"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-23541"},{"type":"WEB","url":"https://github.com/auth0/node-jsonwebtoken/commit/e1fa9dcc12054a8681db4e6373da1b30cf7016e3"},{"type":"PACKAGE","url":"https://github.com/auth0/node-jsonwebtoken"},{"type":"WEB","url":"https://github.com/auth0/node-jsonwebtoken/releases/tag/v9.0.0"},{"type":"WEB","url":"https://security.netapp.com/advisory/ntap-20240621-0007"}],"affected":[{"package":{"name":"jsonwebtoken","ecosystem":"npm","purl":"pkg:npm/jsonwebtoken"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"9.0.0"}]}],"database_specific":{"last_known_affected_version_range":"\u003c= 8.5.1","source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2022/12/GHSA-hjrf-2m68-5959/GHSA-hjrf-2m68-5959.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:L/A:L"}]}
