Overview

com.jason-goodwin:authentikat-jwt_2.10 is a simple scala-jwt library.

Affected versions of this package are vulnerable to Timing Attack. A time-sensitive equality check in the JsonWebToken.validate method in main/scala/authentikat/jwt/JsonWebToken.scala in authentikat-jwt allows the supplier of a JWT token to guess bit after bit of the signature by repeating validation requests.
