  -> jsonwebtoken-8.5.1/index.js (Extension)
   -> ❌ jsonwebtoken-8.5.1/lib/JsonWebTokenError.js (Vulnerable Component)

Vulnerability Details

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.

   -> ❌ jsonwebtoken-8.5.1/sign.js (Vulnerable Component)

Vulnerability Details

Versions "<=8.5.1" of "jsonwebtoken" library could be misconfigured so that legacy, insecure key types are used for signature verification. For example, DSA keys could be used with the RS256 algorithm. You are affected if you are using an algorithm and a key type other than a combination listed in the GitHub Security Advisory as unaffected. This issue has been fixed, please update to version 9.0.0. This version validates for asymmetric key type and algorithm combinations. Please refer to the above mentioned algorithm / key type combinations for the valid secure configuration. After updating to version 9.0.0, if you still intend to continue with signing or verifying tokens using invalid key type/algorithm value combinations, you’ll need to set the "allowInvalidAsymmetricKeyTypes" option to "true" in the "sign()" and/or "verify()" functions.

  -> ❌ jsonwebtoken-8.5.1/index.js (Vulnerable Component)

Vulnerability Details

jsonwebtoken is an implementation of JSON Web Tokens. 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 will result in incorrect verification of tokens. There is a possibility of using a different algorithm and key combination in verification, other 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. If your application is supporting usage of both symmetric key and asymmetric key in jwt.verify() implementation with the same key retrieval function. This issue has been patched, please update to version 9.0.0.

Vulnerability Details

auth0/node-jws is a JSON Web Signature implementation for Node.js. In versions 3.2.2 and earlier and version 4.0.0, auth0/node-jws has an improper signature verification vulnerability when using the HS256 algorithm under specific conditions. Applications are affected when they use the jws.createVerify() function for HMAC algorithms and use user-provided data from the JSON Web Signature protected header or payload in HMAC secret lookup routines, which can allow attackers to bypass signature verification. This issue has been patched in versions 3.2.3 and 4.0.1.
