CVE-2022-23541
jsonwebtoken's insecure implementation of key retrieval function could lead to Forgeable Public/Private Tokens from RSA to HMAC
描述
# Overview Versions `<=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. # Am I affected? You 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. # How do I fix it? Update to version 9.0.0. # Will the fix impact my users? There is no impact for end users
