Type confusion

fast-jwt provides fast JSON Web Token JWT implementation. Prior to version 3.3.2, the fast-jwt library does not properly prevent JWT algorithm confusion for all public key types. The 'publicKeyPemMatcher' in 'fast-jwt/src/crypto.js' does not properly match all common PEM formats for public keys. ...

CVE-2023-48223

fast-jwt prior to v3.3.2 contains a publicKeyPemMatcher bug that fails to cover all PEM formats for public keys, enabling an algorithm-confusion attack (HS256 signed with an RSA public key) when RS256 is used and the verifier does not explicitly specify an algorithm. A patch in v3.3.2 fixes this ...

Json Web Token (JWT) Bypass

json-web-token is vulnerable to Json Web Token JWT Bypass. The vulnerability is due to an insecure mechanism used while verifying the signature of a JWT. The library blindly trusts the algorithm listed in the token without further verification. An attacker can forge a token using the HS256...

GHSA-4XW9-CX39-R355 json-web-token library is vulnerable to a JWT algorithm confusion attack

Summary The json-web-token library is vulnerable to a JWT algorithm confusion attack. Details On line 86 of the 'index.js' file, the algorithm to use for verifying the signature of the JWT token is taken from the JWT token, which at that point is still unverified and thus shouldn't be trusted. To...

CVE-2023-48238

CVE-2023-48238 affects the javascript library joaquimserafim/json-web-token. The root cause is that the library’s verify flow uses the JWT-supplied algorithm (potentially HS256) before the token is verified, enabling an algorithm-confusion attack against applications using RS256. Attackers can cr...
