CyberRota Analysis
AI-GeneratedA vulnerability exists in the OIDC token introspection endpoint of Keycloak's keycloak-services component, where a confidential client can receive full token claims for a token issued to a different audience. This flaw allows unauthorized clients to bypass audience restrictions and potentially access sensitive information. Organizations using Keycloak for identity and access management should prioritize patching this vulnerability to safeguard against unauthorized data exposure.
Original NVD Description
A flaw was found in the OIDC token introspection endpoint of the keycloak-services component. Keycloak is an open-source identity and access management solution used to secure modern applications and services. The issue occurs when a confidential client, configured to receive signed JWT introspection responses, attempts to introspect a token issued for a different audience. Although the endpoint correctly identifies the token as inactive for that client, it still returns the full set of token claims within a signed JWT field. This allows an unauthorized client to bypass audience-based restrictions and access sensitive information contained in the token.
