Security Advisories 🚨

🚨 jsonwebtoken's insecure implementation of key retrieval function could lead to Forgeable Public/Private Tokens from RSA to HMAC

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) 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

🚨 jsonwebtoken vulnerable to signature validation bypass due to insecure default algorithm in jwt.verify()

Overview

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.

Am I affected?

You will be affected if you do not specify algorithms in the jwt.verify() function

How do I fix it?

Update to version 9.0.0 which removes the default support for the none algorithm in the jwt.verify() method.

Will the fix impact my users?

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 unrestricted key type could lead to legacy keys usage

Overview

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.

Am I affected?

You are affected if you are using an algorithm and a key type other than the combinations mentioned below

Key type	algorithm
ec	ES256, ES384, ES512
rsa	RS256, RS384, RS512, PS256, PS384, PS512
rsa-pss	PS256, PS384, PS512

And for Elliptic Curve algorithms:

alg	Curve
ES256	prime256v1
ES384	secp384r1
ES512	secp521r1

How do I fix it?

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.

Will the fix impact my users?

There will be no impact, if you update to version 9.0.0 and you already use a valid secure combination of key type and algorithm. Otherwise, use the allowInvalidAsymmetricKeyTypes option to true in the sign() and verify() functions to continue usage of invalid key type/algorithm combination in 9.0.0 for legacy compatibility.

🚨 jsonwebtoken has insecure input validation in jwt.verify function

Overview

For versions <=8.5.1 of jsonwebtoken library, if a malicious actor has the ability to modify the key retrieval parameter (referring to the secretOrPublicKey argument from the readme link) of the jwt.verify() function, they can gain remote code execution (RCE).

Am I affected?

You are affected only if you allow untrusted entities to modify the key retrieval parameter of the jwt.verify() on a host that you control.

How do I fix it?

Update to version 9.0.0

Will the fix impact my users?

The fix has no impact on end users.
