CVE-2021-41106: Insufficient Verification of Data Authenticity

JWT is a library to work with JSON Web Token and JSON Web Signature. Prior to versions 3.4.6, 4.0.4, and 4.1.5, users of HMAC-based algorithms HS256, HS384, and HS512 combined with Lcobucci\JWT\Signer\Key\LocalFileReference as key are having their tokens issued/validated using the file path as...

JWTweak - Detects The Algorithm Of Input JWT Token And Provide Options To Generate The New JWT Token Based On The User Selected Algorithm

With the global increase in JSON Web Token JWT usage, the attack surface has also increased significantly. Having said that, this utility is designed with the aim to generate the new JWT token with little or no time which would help security enthusiasts to find security flaws in JWT implementatio...

CVE-2021-29157

CVE-2021-29157

CVE-2021-29157 affects Dovecot before 2.3.15. The issue is a path traversal vulnerability that, when an attacker has local filesystem access, can trick OAuth2 JWT validation into using an HS256 key from an attacker-controlled location during local JWT validation with the posix fs driver. This can...

Signature Verification Bypass in jwt-simple

Versions of jwt-simple prior to 0.5.3 are vulnerable to Signature Verification Bypass. If no algorithm is specified in the decode function, the packages uses the algorithm in the JWT to decode tokens. This allows an attacker to create a HS256 symmetric algorithm JWT with the server's public key a...
