AI-GeneratedA vulnerability in Keycloak allows an attacker with a valid Microsoft token from an unrelated organization to bypass tenant restrictions when using the token exchange feature, potentially leading to unauthorized access to sensitive data within the Keycloak realm. Organizations utilizing Keycloak for Microsoft account logins should prioritize addressing this issue to mitigate risks of data exposure and unauthorized actions. Immediate action is recommended for those managing sensitive information or relying on Keycloak for authentication.
Original NVD Description
Keycloak provides a way to let users log in using Microsoft accounts while restricting access to a specific organization (tenant). A flaw was discovered where this restriction is ignored when using the token exchange feature. This means an attacker with a valid Microsoft token from a completely different organization could gain access to the Keycloak realm, potentially accessing sensitive data or performing unauthorized actions.
