NVD Description
Note: Versions mentioned in the description apply only to the upstream ruby-omniauth-auth0 package and not the ruby-omniauth-auth0 package as distributed by Debian.
omniauth-auth0 (rubygems) versions >= 2.3.0 and < 2.4.1 improperly validate the JWT token signature when using the jwt_validator.verify method. Improper validation of the JWT token signature can allow an attacker to bypass authentication and authorization. You are affected by this vulnerability if all of the following conditions apply: 1. You are using omniauth-auth0. 2. You are using JWTValidator.verify method directly OR you are not authenticating using the SDK’s default Authorization Code Flow. The issue is patched in version 2.4.1.
