CyberRota Analysis
AI-GeneratedA vulnerability exists in the JWT Bearer authorization grant implementation of the keycloak-services component in Red Hat Build of Keycloak, which fails to verify if user consent is required before issuing access tokens. This oversight allows authenticated attackers with valid client credentials to bypass consent requirements, potentially leading to unauthorized access to user accounts at consent-gated clients. Organizations utilizing this component should prioritize remediation to mitigate the risk of unauthorized access.
Original NVD Description
A flaw was found in the JWT Bearer authorization grant implementation within the keycloak-services component of Red Hat Build of Keycloak. This component handles various OAuth2 and OpenID Connect grant types used for issuing access tokens. The issue occurs because the JWT Bearer grant fails to check if a client requires user consent before issuing a token. This allows an authenticated attacker with valid client credentials and a trusted identity provider assertion to bypass the consent requirement and obtain unauthorized access to a user account at a consent-gated client.
