Unrestricted Key Type

jsonwebtoken uses unrestricted key type. A remote attacker is able to bypass signature verification if the library is misconfigured so that legacy, insecure key types are used for the verification. The user is affected if the library uses an algorithm and a key type other than a combination liste...

Signature Validation Bypass

jsonwebtoken is vulnerable to signature validation bypass. The lack of algorithm definition in the jwt.verify function leads to signature validation bypass due to defaulting to the none algorithm for signature verification, which allows an attacker to bypass the verification mechanism...

Improper Input Validation

jsonwebtoken is vulnerable to improper input validation. A remote attacker is able to write arbitrary files on the host machine via the secretOrPublicKey argument from the readme link of the jwt.verify function due to improper input validation. The vulnerability is only possible if untrusted...

CVE-2022-23539

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...

Type confusion

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.
